Internet can get very expensive
Couldn't you just have pulled a fibreoptic cable from one roof to the next or did the landlord not like that?
No problem! Do you know what also isn't a problem? This segway to our sponsor, Glasswire!
Hi linūs
Maybe consider also installing a postal tube for launching SSDs across. Load it up, pack it into a tube cartridge, *thwomp*, it's vacuumed over into the other building, unpack, plug it in, data transfer!
if they had a tube between the buildings, they could just run fiber in it instead
Sounds a bit like a modernized fixed installation of RFC-1149 ;)

Time travel!
As a former tower tech and WISP guy, set the Tx to -4db and auto adjust power off. You'll get a better alignment that way, also some freaking HOT signals between the two lol. I'd also recommend getting a set of Cambium POE surge protectors. We use them on towers quite a bit and they have held up to literally lightning strikes over and over. Highly recommended.
Suggestion #2: During high winds them mounts ain't gonna hold 😂 you need a 6x6ft full of bricks with the mast in the center
Suggestion #3: Your LOS may be getting cut off by the parapet a bit, raise them about a foot or so higher and you'll get a significantly better quality in TX/RX.
Yes do this everything 12GaugeNick said is correct! Horizontal and Vertical Polarization so half your wireless Frequency is getting cut off by the parapet it looks like, which will explain the weirdness in speeds in one direction vs the other! the size of those satellites might be too big as well meaning its overkill for the distance used. Its like standing next to eachother talking with megaphones. You'll blow out your ears so to speak! -50 to -60 dbm is what you want for best results both directions =]
-50dbm is probably the best when it downpours as rain will affect 60GHz and its a very small parabola effect and fresnel zone meaning they have to be perfectly lined up. Use Lasers! it makes it much easier to align at that distance too.
Make sure your WiFi signal on 60GHz is clean too both HQ and Remote (im sure it is but make sure.)
I've shot AirFiber over 42Miles and its incredible to say the least! AF 5HDX (with Monster Antennas) [EF ELEMENTS ULTRAHORNS are probably the best PtP]
Also make sure the NTP servers are set correctly Wireless is heavily time correct dependent. I'm sure the GPS Geosync will also ensure this but for maximum efficiency do it for the best internets.
Also check they are level as polarized signals present as interference if they don’t both align.
Better again move to Cambium gear e.g. cnWave would do a 3 way bridge between your buildings using 60GHz or licensed links using eband would be able to do 40Gbps each with gear like Aviat that doesn’t cost what you might think.
Suggestion #4: Should have just run a cable between the buildings over the parking lot just like they do with power lines, don't have to worry about any trucks hitting it, since it's high enough...... But yes it would void the reason for the video with dishes, but would work better though
@@friesm2000 I think it might be over 100meters though as the cable runs and would technically probably break the TOS for their offices. Unless doing Fiber which would be equally as expensive if not more so and labor intensive to be built to code with permits to not break TOS.
@@friesm2000 considering the buildings are part of the same complex pretty good chance there are ducts underground running between the buildings. Just run fibre 😇🤓 ofc that’s pretty boring and this a TH-cam content company 🥳
they need to be higher, or at least on the edge of the rooftop, the signal is affected by the Fresnel zone
Solution 1: a longer post.
Solution 2: bring them closer to the edge of the roof, thus avoiding signal bounces and interference due to the proximity of the ground
I was about to say the same... botton fresnel is affected for sure and can cause problems with each polarisations and making final throughput lower or fluctuating.
Placement can be better + test other channels, reduce TX power and enable channel bonding.
@Defcon87 With how close the two devices are (around 100m) and with the link operating at 60GHz, the freznel zone is tiny enough (estimated to be around 50cm radius) that the rooftop shouldn't interfere with the freznel zone. 5Ghz however probably would be affected though.
I know nothing about how frequencies in this range are reflected by objects on the ground, but I imagine there are all sorts of weird reflections off of items on the roof. And with the antenna that close to a ground plane with the wall at the edge and a gap between the buildings, I'm not even sure what that would do. I bet raising the antenna just 2ft higher off the roof would make quite a difference in consistency. Would be interesting to see what the error correcting mechanisms are actually seeing and doing. Edit: everything I said is speculation...
Fresnel at 60Ghz is so tight and narrow I doubt its the issue, running the PTP at -30 is definitely not a smart idea, both antennas are basically screaming at each other which could be causing signal wash. The signal would improve dramatically if they'd lower the output power and aimed for -45 or -50dbm, I would never leave a dish at anything below better than -45dbm you're asking for issues down the road.
Not tech related, but it shows he's gotta be a good boss when he takes responsibility for the wrench incident instead of blaming it on the person that threw it.
It would have been funny if it hit Linus' car.
He did tell them to send it, on camera
He would be even better if he would contact the person who's car it was...
@@FinlandApollo Supposedly he did that between the camera shots considering that he already "spent $1k" on it.
@@m0nkeyman911 he could have literally had that edited out if he had wanted to
The speed jumping to 1Gbit and then higher is probably the dishes jumping between 5GHz and 60Ghz. VHT160 5Ghz is about 800-950mbit. Probably look at getting both of the dishes mounted higher, likely the fresnel zone is getting cut off being so low to the roof.
Yeah this!
Fresnel zone will be causing a few issues with this install
This^
Raising the dish will also help prevent distortion from snow in the winter.
Yep, I kept telling myself the dishes needs to be raised higher. Hopefully they will see this and try again.
From the spec sheet, the 60XG doesn't support VHT160 only up to 80. The 5Ghz radios are only for backup, in case 60Ghz radios have trouble.
My guess is on a flaky termination of the cables runs. The radios are reporting almost 6 gigs of capacity, so the problem doesn't seem to be them.
I am certain a lot of us was terrified for a second and then incredibly impressed at how Linus was holding that laptop on the corner alone....and still didn't drop it.
I immediately cursed out loud when I saw that.
@@rawrgrr1273 yeah that did not look safe at all.
exactly man, I just panicked when I saw it
I panicked, then remembered…he can afford it
Also terrified for not wearing “safety” gear like a hard hat etc, but then again it wouldn’t do shit
I'm sure you guys know what you're doing so this info is maybe more useful to others that are installing PtP radios. I'd be curious what the signal gain is on the radio, -37dbi is quite high for that short of a link. Usually you'd want to aim for -50 to -60 if possible. You should make sure you aren't oversaturating the radios as too high output can cause the uplink and downlink to interfere with each other similar to someone shining a flashlight in your eye while trying to read words off a page. Also, performing a spectral analysis is a very useful step as well. The uplink and downlink carrier frequencies can't use the same frequency, so it's possible that one of those frequencies has more interference in the surrounding environment. You may be able to change to another channel to get closer to a 6G link and additionally choose a wider channel width if the interference in your area allows for it. Check to see what the MCS methods are for up and downlinks. If they aren't at 15 then you probably have an interference issue.
Look into "fresnel zones", as others have mentioned, the edge of the building may be causing a problem with the vertical signal.
Anyway I'm no expert but I've been installing Ubiquiti PtP for close to 5 years and that's just a few things I like to look into.
It's all about modulation. Do a link planner get expected signal and line them up with scopes and fine tune. If your over 10 off expected signal your on a side lobe which is crazy easy to do on millimeter wave by the way. Once you've achieved the best possible signal is when you tweak the eirp and power output to achieve the best modulation. With 5g a -50 is more or less best practice but with and mm wave you want that extra oomph to mitigate rain fade, especially if it's your only connection. But as close as it is rain fade should be minimal. Just my 2 cents. Been installing ubnt gear since around 2010 when they came out.
Just what i wrote... :D
This would be interesting for them to cover.
Just a tip for next time installing a wifi bridge, those thing need some clearance from the floor, technically you need to leave at least 80% of fresnel zone free (a imaginary elliptical tunnel), eyeballing the distance a bit at 60ghz is about 1 meter so a pole 1,5 to 2 meter should do the job, with the backup frequency at 5ghz is about at 3,6 meter. Also you should consider the reflection of the floor can inject into the wifi bridge but the irregular not metallic floor should be enough to ignore it. Hope it helps. Source? I installed few of those bad boys.
Always love a networking-related video, especially miss the old server vlogs
I guess with how few of them lately says something about stability
ME TOO!!
We will get more content soon, something will break 🤣
Fax
@@scott2100 v true
The antennas are too close to the roof, so there is a substantial reduction in signal quality because fresnel zone... I bet raising the antennas 3 more feet will make the connection even faster... Also since those antennas are rated for long ranged you should reduce the power to the bare minimum... I bet Ubiquiti can help tune them for you
YES! Know your Fresnel zone!
I don't think they are for long distance, at work we used some other brand that also use the E-Band for high capacity and the recommended distance was about 3 Km. The ones we have are 2 Gbps but we are looking at getting other brand that has 20 Gbps over the air, cant remember the distance on those but is not that long distance either. Alignment on those kind of antennas is like turning the alignment bolt 1/8 of a turn each time and wait a few seconds for the radio signal to stabilize, and they moved so much each time, it's so close it doesn't matter that much but -38/-44 on a yelling distance is not that good
Exactly my first thought when I saw the stand they were putting it on. Fresnel zone!
could also move them closer but sometimes if they are to close it hurts performance
@@marcogenovesi8570 Chill out felecia
please more networking stuff !
I really enjoy these kind of videos from LTT
Funnily enough I used to work in the development department for a company in Scotland who are well known for selling used cars.
The IT guy told me In their new build HQ they were still waiting for a connection from BT (British Telecoms) so in the meantime they used a building they owned not far away (literally across the road so I hear) which had a fibre link and set up a satellite link between the new HQ and that building. Worked very well.
wtf would they do a satellite link when you can just do point 2 point like in this video?
@@gg-gn3re I presume that satellite in this context just means a remote connection not a connection to a satellite in space. In other words it was likely exactly the same kind of thing LTT did.
Something to try. As backwards as it sounds, turn the broadcast power to the lowest setting, -4bd or so, since the distance is so short it could be distorting because it is too "hot"
100 percent
Yeah anything past -50 is too hot with most Ubiquiti gear in my experience. Auto power management usually works for us, though. (WISP with about 800-1000 customers)
Absolutely. Hot radios can actually burn out
We thinking the same thing. Get the rsl closer to -50. We don't use ubiquity, but we're fine down to -80 across 20 miles
And lift the damn dishes up several feet. Half their Fresnel zone is roof. Lol
I work at a company where are core infrastructure is providing wireless internet options as a network provider. This solution is diffidently 1000% overkill, but I love it
I diffidently disagree
What kind of systems do you use at your company?
I like how they stressed about using not rated for outdoors cat cables :D meanwhile in RL i have seen in dozen objects with 20+ year old indoor cat cables exposed to +30C summers and -30C winters for over 2 decades still running 1000mbps without any interuptions

Mad props to Linus you the man pulling that up alot of people scared of roofs plus pulling something like that up feels like 5X the weight that it is and pulls you real hard. I did alot of HVAC and pulling a twin scroll compressor onto the roof the same ways is real tuff and scary at the point when you have to move to grab it up. You did a supreme job so props again. Love u guys
I was scared watching it lol
Idk if his insurance would have covered an accident like this one xD
I was scared too.
Thanks for sharing your experience Linus and the team ❤️❤️❤️
I love how Jake just chews Linus out for asking someone to throw the wrench up when the wrench hits someone's car XD he just doesn't hold back "You fucking idiots." Priceless
In hindsight, they really should have had three people besides the camera crew, so that someone could run around like a greyhound fetching things.
the mistake that cost Linus $1K... 18:12
Nothing I like more than a 20+ minute video with Jake and Linus installing networking gear, seriously
I love these vids with Linus and Jake… ultra crazy DIY. Amazing. Please never stop.
I have only the vaguest idea of what they are doing but I watched the whole thing cause I absolutely enjoy watching them do it. Would love to have this must fun on a project.
As a server guy, please test the link speed with iperf. File transfers are always limited of disk speed and software limitations, but iperf is designed to be used as server to server speedtest, so shouldn’t have any such limits. And it is preinstalled on your TrueNas box. I believe that the sudden jump in speedtest net may be because the server you’re testing against has already some load and most people have higher download speed than upload so as the server likely has symmetric or fiber, there isn’t as much congestion in upload.
I was just going to write the same. So tired of checking bandwidth testing with file transfer. Iperf is the right way to test network equipment on the cheap ;)
I like when they test the Speed with file transfer, because that's what you use it for in everyday life
iperf is my favorite DDoS tool XD
@@sucotronic the file test is to there own full ssd server which i believe can saturate 10g networking.
@@bitnarrator but it's not reliable as a benchmark for the quality of the link
I just wanted to note that that radio has an SFP+ port and they installed an ethernet module. While it works, given the opportunity I would have suggested using fiber modules instead. Lightning can't travel over fiber. You would still need to provide the 1G POE connection to power the radio but that is much easier to send off to an isolated switch and not plugged into the main network. Fiber is way better than any lightning/surge arrestor that has ever been made.
yep
Or a cheap Poe injector
The second I see the intro, this similar thought was crossed in my mind. Is this a joke? Or just another sponsored content?
I bet you the SFP module Jake bought wasn't fully compatible and the connection will become flaky. He'll probably just put in another SFP ethernet module though.
@@veryboringname. yeah... It's already failed.. they talked about it on the wan show 😂
I did this back in 2012 when we had 3 units in the same complex, two were next door to each other and one was around 600 ft away across the parking lot...Worked great for a couple of years, the building only had crappy copper wiring that was falling apart so we had to run our own copper back to the MPOE so we didn't even have another option really of getting a second connection.
I love the Linus / Jake synergy. The roasting is just hard enough and not over the line. Makes me addicted even more than before.
I installed a few older models of these a couple of years ago, not the 60 ghz one, but 5 ghz and 20 ghz. What I think is happening here is the 5 ghz is connecting well but the 60 is not. The 5Ghz is giving you the 1 gigabit and every now and then the 60 happens to connect and give you more. At that range the 60 beam would be so tight it would probably just be like 2-5 cm. The farther away you are the wider the beam spreads so being too close can make it harder to align. As you got 3 gigabit for a while you are probably really close to the 60 working, it just needs to be fine tuned. The dips below a gigabit that you were getting are probably from the Fresnel zone of the 5 ghz, it would be around 2 meters at that range, so it is bouncing off of the roof a bit. Ideally your dishes need to be a bit higher up, but that would not matter if the 60 was connecting solidly, as it's Fresnel zone would be less then .5 meters at that range.
To get the 60 aligned I would recommend to set up a script that keeps a constant file transfer going and a way for you to monitor the speed while you are on the roof, then to just turn the knobs on the dish a tiny amount at a time from both sides. Wait a bit to see if anything changes then keep doing it until you get it. Considering how tight a 60 ghz beam is it could take hours. I never worked with anything more then 20Ghz and even that was a pain sometimes. With 5 ghz you can usually just eye it and it is fine, but it can take hours to get a 20 lined up well, especially if you are too close. One time on a close 20 ghz link it took us 3+ hours to get it aligned and you guys are even closer and using 60, so it could be really tedious. I really wish that this sort of dish came with a perfectly aligned laser mounting point on them, so you could clip on a laser dot and just line up the dot to a target point on the other dish.
To start off they need a more solid base to mount it to. And yes high frequency is horrible to align. Done some 80ghz kit links around 2 miles, it's so sensitive that you notice a quarter turn on the fine adjustment and also see it change when you try and lock it off after you've finished fine adjustment.
Can take a while to even get a link initially, even if it looks spot on.
The kit I've setup had a special plug to connect a multimeter to, it gave out a small voltage which allowed for near real time monitoring of signal while adjusting.
I would be interested to know if the ubiquiti kit shows a signal levels for both 5ghz and 60ghz, I would assume they would or it would be near impossible to align the 60ghz properly.
A mounted laser would be a bit pointless at the ranges these can do, but often there is a mounting option for a scope to do the initial alignment.
IIRC these come with an alignment crosshair that they just straight up didn't use lol. You can also DIY a headphone adapter to plug into the aux port and adjust by tone, just put on some headphones and tweak it around while listening. Sounds way easier than keeping one eye on link speed.
They can just use lasers to speed up the process you mention to instantly.
This was the comment I was looking for. That fresnel zone though.. have an upvote
Except use iperf instead of the file transfer :)
I could watch a whole channels worth of Jake and Linus' networking adventures, they're always the best videos lol
Anything with Jake and Linus "adventures" is fun to watch.

@@jeepdog5 its a Canadian thing lol
It's such a big bro lil bro relationship 😂
They're good. But I get irritated everytime Linus says "boys". People talking like that irritates me. I'm a grouch
I used to run the network on a campus that had six buildings with Ubiquiti Wi-Fi bridges between them and they were rock solid. One pair was even some of their oldest 100Mbps units that were in operation for probably close to a decade.
Idk why but it just makes me so happy to see you guys grow and have so much fun. I love seeing people succeed.
Linus: "But that would cost money and I already spent it all"
Yvonne: "I will send you a house warming gift"
Seeing how everyone is getting more comfortable/confident being on camera from where they first started. Shows how much everyone is growing as individuals. Great to see everyone finding their true roles
gettin them prepped for the inevitable day that Linus retires
5:07 I used to carry large dishes and cinder blocks up on roofs like that a lot, usually we took a long rope and tied the object in the middle and had one person up top pulling up while the other would lightly hold the other end about 15 feet away from the building and keep the object from scraping the side of the building, this worked pretty well but it certainly gets to be a struggle after a while once you have to haul a dish, sled and 8 cinder blocks up
Man something about LTT vids just makes me happy. Thanks
This style of video is great to get from you guys sometimes. More laid back, some more bleeps, and messing around. Just a couple tech nerds yelling at each other while setting up tech. Loved it.
That dish alignment could have been so much "user friendly" with a strong laser pointer.
Gets big stick.
Anything over 5mw is too strong for users and illegal in some places tho
@@DontDoubtOurServers for this distance a 5mW laser pointer is good enough.
*Was about to say the same although a normal laser will be enough hold it in the middle of the dish and see if it hits the other dish the same.*
Thinking the same thing lol
these infrastructure videos with Linus and Jake are my favourite LTT videos
For this microwave Connection you should use an higher Pole because of fressnel zone of 15° in the coil, you might can get reflections. When it rains it should modulate down and work further.
But nice to see, iam working with these technigues in germany for mobile phone providers :)
It's crazy to see how fast you guys are growing. Almost 1 year ago, you did a studio tour and now you're adding 2 more units. 1 of them is just for MERCH. It's crazy!

I will never not love Linus and Jake's antics, truly the highlight of this video
Edit: Linus (the child) getting Jake (the responsible adult) to actually throw him his wrench and it still falling, and hitting someone's car is genuinely the best thing I've seen this week and it's only fucking Monday
And he didn't even need the wrench to begin with
i love it, looks like a the office scene
I think probation guy threw the wrench, Jake is just there standing still at 16:01
aww I got spoiled before seeing it myself
@Garrus Vakarian I think that's why he looked down at his wrench and said "that was totally the best thousand bucks i ever spent" after they didn't even accomplish anything lol
As a local vancouver roofer I feel like letting you know you should be putting type 4 extruded insulation down under those things on the roof without a layer of insulation for protection itl break through the rubber over time. haveing it on the rocks would be better then not haveing them. Also dont let worksafe see this video they would love to fine ya for working next to the edge without proper fall protection.
Might not be a coincidence that the only person shown near the edge is the guy who owns the business - i.e. _not_ an employee 😉
Otherwise, I really feel like they need to talk to you plus a couple of the more knowledgeable wireless installers on here to get their sh$t sorted out. My wireless installation days are 25 years behind me at this point, and I never got a ton of reps at it anyway 😅
Genuinely it'd probably just be better to punch through the roof and attach directly to the deck. You're gonna pay for the penetration one way or another, might as well do it right to begin with, and maybe get a taller mast to clear the parapets better.
Ha I just googled about what those rocks ballast do on the roof (always wanted to know) since the ones on that building looked rather large. After reading up on them and seeing Jake say he was going to move them out of the way I wondered if it would cause problems down the line.
I’m a single ply roofer from Scotland just wondering do yous use sarnafil much over there ? If I’m doing a green roof or slabbing over it I will use alwitra membrane
@@JamesCarter1888_ Sarnafil exists over here in the US, it's a pretty high end roof though. Usually we use domestic manufacturers, mostly TPO, EPDM and still some BURs.
FYI physical alignment over that short a distance is much easier with a laser pointer and a target fixed to both dishes. simple easy and no guessing. i have done this several times for smaller distributed dishes on farm buildings separated by more than 250 yards
Those NPRM's are way under rated for that large of a dish. 2 cinder blocks vs the torque created by a light wind on that parabolic dish. You will be out of alignment first wind you get.
14:10 my heart rate took a lil jump watching Linus handle that laptop
Used to work in line of sight comms. The comments about increasing the height and reducing the transmit power of the antennas are correct. and at this distance, the fine alignment needs to be done really slowly, like maybe 1/8th of a turn of the knob, not several turns at once.
the mix between sketch and legitimacy with this install is the perfect balance, and is exactly what i expect from LMG.
I don't get everything you guys talk about in your various videos, but, I love the ones where you're "doin' stuff!"
You know a 2 dollar laser would've helped aim them to align them perfectly.
Shout out to the crew that will come in once filming is done to clean up and seal it properly.

Linus is cheap, he isn't paying for someone to do this unless it is Jake and I'm sure we all know that Jake is going to perfect this
@@KingLarbear Do you think the 1000 dollars Linus paid the person is enough to cover the damages to the car?
I really like the lighting on the rooftop
After seeing The New Guy in like five videos now I am overflowing with glee every time I see him now. Which I'm very glad about because Linus has had some great people come and go and I'm glad to see someone I like so much that seems to be sticking around! :D
which one?
Something to note, with these ballasted EPDM roofs I would highly recommend putting a rubber pad beneath those dish stands. The membranes are pretty thin and leaks can run underneath the membrane which makes it very difficult to locate leaks, putting down pads could save major headaches in the future.
Yup, I've done a few free-standing roof mounts and when I saw Jake moving the stone I was thinking the same thing.
Shh-shh-shh! They did that intentionally so they'd have future content!

they're yelling at each other over the rooftops
while holding phones..
big brain battery saving strat boys 👍
Gotta exercise thise vocal chords lol
If it was windy that's probably why, phones aren't great at blocking out wind noise. Walkie talkies or yelling is generally better :)
I loved that head wear made of wire!
Nice to see you'll are moving up congrats guys I always enjoyed you'lls tech shows 😎🤟 definitely a nice idea for free internet especially if your old building is right next to you
"Come with me, and you'll be in a world of OSHA violations"
Fun fact: Canada has zero OSHA violations.
@@jordanclock but they have a ton of OH&S ones.
Can only imagine the employees reaction when Linus walks up to them at their desk. "So listen. I hit your car with a wrench. Here's $1,000. Sorry."
The building is shared between several companies, isn't it? I wonder if it's even one of their employees' cars. Might be someone unrelated entirely.
@@SianaGearz it says its a LTT employee's car right in the video
@@ThebigFlanc Where'd it say? I didn't see/hear that
@@ThebigFlanc did it?
He actually says something like "a boss from another department damaged your car", referring to himself. so the car should be from someone at another company, not his employee.
This video gave me a flashback to my days before getting into Computer Science. Used a IT Technical Support course as a stepping stone and we had to do Ethernet cables, making them from the wire and the connector. Mine ended up being like an inch or two long..it was horrible. Never looked back..
Great video, was really wonderful!
Can you do a follow-up video, where you put the dishes closer to the edges of the roofs?
It might be that the dishes use e.g. horizontal polarisation for the one direction and vertical for the other. In this case the waves are differently scattered and diffracted on the roof edges, which would explain the asymmetric speeds ;)
The like 30 seconds of Linus talking from the perspective of the Ethernet cable may be the best content this channel has ever uploaded.
Ending it by responding to the cable "you're an inanimate object, no one cares how you feel" was gold
Have you not seen the fire truck?
Jake and Linus videos are always so fun to watch. You two are the perfect kind of no-filter-chaos xD
i miss jake being in the channel so much i havent seen him in one in years
@@billyhatcher643 you don't watch enough then lol
I wonder if having the dishes on higher poles would increase their abilities, honestly for that matter I wonder what speeds would have been like if they were placed point blank in front of each other. Maybe a minimal distance is required, but still basically wonder if they could have ever lived up to the max speeds they claim.
I love seeing you guys use Ubiquiti stuff! If you want to try another good product for PTP "air fiber", the Mimosa B24 is great. Gig speed but less worry about rain fade and a MUCH smaller footprint.
I install these dishes for a living, typically with a dish like that -36 is as good as you can, unless you raised the pole for less building interference. Good job!! :)
My ideal for a link like this would be to keep it ABOVE the 30s... -40/-40 would be ideal, at lowest power, with the dang things on a real 3-4" OD 10' tall mount pipe and sled. I would never hire these guys to internet up anything. Sooooo painful to watch.
18:30 I'm almost certain that these antenas were placed to close to the roof. If these work in 60GHz band then first Fresnel sphere in half distance of 50meters should have radius of about 35cm. But in 5GHz mode it is about 1.2 meters and that antenas are much lower over the roof.
I've done quite a few of these building to building dishes. Use a laser taped to the top of each dish to get the alignment right.
I would love to work with Linus! His sarcasm and dark humor make this 100x better than any other tech channel.
As someone who worked on roofs as a job and had fall certification for several years, I want to very much tell everyone DO NOT DO ANYTHING THEY'RE DOING IN THIS VIDEO lol
100%, it could've taken Linus just ever so slightly adjusting his center of gravity a bit and he could've gone over the edge 😱
@@meeguelangelo lmfao every time he does this I remember all the horror stories I heard from career trades guys and tug at my collar a little
There’s “fall certifications”...
@@o0julek0o it's a dumb name for important training. just learning how to properly wear harnesses, guidelines for what each situation requires what sort of PPE/safety precautions, etc. you need it if you're doing any work on leading edges without guard rails and such in place.
@@rileyminer9748 a very dumb name. I assume it’s some kind of colloquialism from people who tend to have the certifications?
Jake has gotten so much more entertaining, and, to be frank, not annoying in these vids since his early days.
He was annoying? Lol
@@J4ckKun yeah.
@@J4ckKun people just didn't appreciate his humor in the early days. He is exactly the same lmao
The sad part about it is he is knowledgable (especially in Fiber Optics) so I can see why he gets to stick around. Sometimes the cringe is too much though.
Well true, but still....the pornstache.
i think an easy way to line them up really good would be to go up at night and use laser pointers attached to it or if it uses a view finder to point the laser though the view finder and you should get very accurate results
I was looking into the comments to see if someone was going to mention this lmao
I Had the same idea
I can't beleive I missed this video when it came out!
Hey Linus you need a earth cable to the earth point on the lighting protection for it to work
I love when Linus + Jake decide to momentarily go Hyper-Canada.
This is something I setup all the time for work, but we install them on towers and utilize band 43/48 too.
Honestly Guys! For ALL the tech knowledge you deal with.... Your "installation skills and methods" are primative!
Imagine working near these guys and hearing this all day from the roof 😂 PS I'd park somewhere else if I saw them coming too :P
That was uncalled for, I want to know if it was a probationary employee or a person on legit probation that threw the wrench
@@mattschwartz7583 im sure linus payed for teh damages cause he told them to through it to him in the first place
@@yamisniper I mean how can anyone blame the employee? Even Jacob told Linus that was a stupid move. Linus can be too cocky and arrogant douche sometimes. He has 3 kids ffs.
I mean he did said "that was the best thousand bucks I've ever spent" so yeah, he must have paid.
@@kiyomiku yea lol
I'm guessing that LTT doesn't have a safety department. That step ladder use would get our safety staff in knots.
ETA: ok, that wasn't even the worst issue.
I think throwing a wrench up to a roof, missing and hit a car was also pretty lit 🔥
Idk man, the hoist was pretty fun lol
that was insane to watch him hoist that thing up
@@jrcowboy1099 Peak danger was probably when he decided to give up his relatively safe, seated position to lean over the edge and grab the 30lb dish with one hand.
I would rather work in these conditions, compared to my current workplace.
Where I work we're forced to watch a one hour safety video, followed by a 2 hour practical training, after which my boss becomes so impatient that he's rusing everyone whilst standing on top of a roof...
There is a certain point where the amount of safety precautions become counterproductive, making work more dangerous rather than less...
I did the same with 2 house here in Venice, for sure I don't have your need requirement of crazy speed but just a good and stable connection without pay unused money for a new line. Price for device i decided to buy 2 CPE210 from tp-link (I know.... is bad... but here in Italy is cheep) they are only eth100 and 2.5ghz, but i told you is good enough for me.
I found difficult to find cheap stands to use for mount the antenna, in the end i crafted one with some L brackets... very very hard to fine tuning the alignment, -54 for the horizontal and -58 vertical! Good enough!
It's all about modulation. Do a link planner get expected signal and line them up with scopes and fine tune. If your over 10 off expected signal your on a side lobe which is crazy easy to do on millimeter wave by the way. Once you've achieved the best possible signal is when you tweak the eirp and power output to achieve the best modulation. With 5g a -50 is more or less best practice but with and mm wave you want that extra oomph to mitigate rain fade, especially if it's your only connection. But as close as it is rain fade should be minimal. Just my 2 cents. Been installing ubnt gear since around 2010 when they came out.
Linus made a great point about ISPs, I have at&t and its a huge pain
At&t is a scam our phones always say we have 5g but it's painfully slow
@@fireballyt3676 we switched to T-Mobile because it was cheaper then att and unlimited my 5g one so much faster when it uses 5g it's crazy+ it now gets signal in areas it used to not get reception.🥰

As someone who used to install a ton of Ubiquiti point-to-point equipment, I can verify this is 100% the Ubiquiti recommended installation process 😂
Can one of you Ubiquiti installer types _please_ reach out to them and fix everything they did wrong? I think I've counted more than half-a-dozen installation fails and I'm _definitely_ not a pro 🤣
i have indoor rated cable running about a 100ft down my garden to my man cave and its been there about 5 years it also has 3 joining connections in it and its been sat there in rain,snow and everything and its been fine lol
working for these guys must be the best job in the world lmao always f'in around yet making great content
It's always nice to see the LTT folks having fun when working on stuff and making videos
And breaking someone's car
I haven't seen anyone mention this, so I'll just add - instead of doing performance testing using online tools / file transfer. You can use a nifty little open source utility called iperf and you wouldn't have other bottlenecks affecting your bandwidth test.
This is a level of DIY I think any of us techy types can identify with. Cranes? Hoists? Nah, rope and out of shape computer geeks. Love it.
YOU guy is the best.. love all you vidieos
I once inherited an infrared laser inter-building connection like that, and it sucked beyond any description I could use in writing.
The two buildings had completely different construction types and therefore, expansion rates as temperatures changed, and to align it you had to put on infrared protective goggles, and use an IR sensitive "target" which made the dot visible - with one person on each roof (itself a complex arrangement on one end due to security arrangements), you then had to tweak the vernier screws on each mount to centre the infrared beam from each in the centre of the target receiver (which was only visible to the person on the other roof, so communication was essential - back in the early days of hand-portable cellphones this was a big deal, and our department had exactly two, never to be allowed out of the office, and just for doing this regular realignment. With all the incoming WAN connections in one building (256kkbit/s to larger sites and 64kbit/s to small ones) and the main servers in the other (political decision), it was a chronic single point of failure in the whole national network of a major utility. Twice a day, minimum, we had to adjust those cursed things and my first action on inheriting them from my predecessor (guess why I replaced him) was to order a pair of diversely routed dark fibre connections between the buildings, with suitable transceiver equipment to translate to our 16Mbit/s token ring between copper and fibre at each end. Network availability jumped from 55% (essentially unusable) to >99.9% instantly on the first of the pair of routes being commissioned, and I got a very nice bonus :-) We were never able to get to the magic 99.99% availability as occasionally the WAN links would reset :-(
It was in making this suggestion at project meetings and having it dismissed by my predecessor (while the team manager was present) that I became a network manager - a considerable promotion. It has taken about a quarter of a century for the technology to be ready for prime-time deployment, and we were the poor suckers that were at the bleeding edge. I later deployed the very first token ring switch (developed by Madge) on the same network. I still kinda miss the graceful degradation of token-based networking over CSMA/CD which saturates exponentially but fully switched ethernet did cure pretty much all of that.
Adjust twice a day? Wow, grim. Gotta love those multiple points of failure setups, you never know what you might walk into in the morning.
I almost went with the same laser system (about a mile), but there was a chance of decorative trees growing up in the way. Glad I skipped that idea now.

I've found the in-line surge adapters affect your line speed. I'd be interested in seeing what the performance is when the surge adapter is removed from the equation. Of course, I personally prefer optically isolating radios anyways.
Connecting fiber to that SFP+ slot seem like would have made it pretty well optically isolated
@@Gastell0 Only issue is that the dish is POE powered.
@@Darkk6969 Brian the Electrician could probably get power close to the dishes. Also doubles as free grounding for the radio maybe?
@@marcogenovesi8570 The thing is that, in order to use the dishes optically, you still have to supply PoE power. So going that route doesn’t really save much.
@@Darkk6969 The POE was separate from the connection so they could just use the surge suppressor on the POE side of things and use Fiber with the SFP+ port.
this is awesome! I love LInus but I also, do Telecomm for a living this is my world.
I love that the logistics department handled getting the cable over there, but the little bossman is the one lugging a dish that rivals his size onto the roof.
When I was studying, I met a guy that lived in a rural area, he had such bad internet that he ended asking for a custom fiber installation in the hopes of reselling it to his neighbors using this same air-fiber tech, first 2 years or so were all losses, but now he's living out of it.
Anyone can become an internet service provider for customers? Aren't there any difficult authorizations?
@@Gnanmankoudji You have to register your business and workers (if any), and your internet contract has to allow it, but yeah, it didn't look like that much of a feat...
EDIT: You can look it up yourself, it's called Manca Telecom, a small but profitable business.
It pays itself faster than many businesses lol
I watched a video here on TH-cam once about someone in Dillon Beach who ended up doing the same thing kinda for the same reason! Really wicked niche market
At that distance it seems like they could have literally ran a fiber cable suspended between the two buildings. That's assuming it wouldn't violate local codes though.
I was totally thinking about this, but use a harpoon gun to launch the cable across just to give the video a LTT spin.
To run the cable that far through air you would need support cabling to hang it from. Aerial runs don't survive long on their own. Just to go 10ft from my house to garage, I couldn't go under so I went over with conduit. Even doing that, had to cut the conduit in the center, couple it then silicone it to give it enough flex not to ripe off either building as they rise and settle with the ground.
@@eideticex I have 60m fiber drop, with cable rated to about 150m. You need to use the correct fiber cable with kevlar inside, they are called "drop" cables. It replaced problematic 5GHz Ubiquiti link.
@@aaronpreston47 So just to be clear......Your proposing to give Linus a harpoon gun..?!!
@@dadsyoutube9974 True, maybe not a harpoon gun, maybe a Tshirt cannon or a potato gun.
@linus make sure to change the network card port settings to full duplex to get all the juicy bandwidth that's possible.
I bought a 10gbps cable a few days ago and was only getting 10 mbps. little did I know that the new cable for some reason made my ethernet connection on the PC downregulate to 10mbps, once i manually enabled 2.5gbps full duplex it was game on.
