- A quick look at how I turned a cheap TV antenna into something to suck up 4G signals from far away. It's quick, dirty, and could probably be improved - but it works!

It would definitely work!!! Great, I have also made many of them, they all work well
This honestly has me tempted to try using an adapter on my RVs old Antenna. If it doesn't work? Oh well, I already have two different cellular antennas. But being able to just re-purpose the old TV Antenna would eliminate the hassle of setting them up. Since I don't have a way to mount them anywhere yet.
Haha, "however, since I'm a bit of a nerd" - LOL, that was the understatement of the century! ;)
Ever so slightly nerdish.
FFcossag you mean nerd*y*. the -ish ending is more to say that something is like "it" (whatever the word in front of it ist) in a "kinda sorta way".
Seegal Galguntijak That's the joke, lol.
old satellite dishes with the offset feed also work well. just tweek the distance of the receiver from the dish itself to get the focal point.
What type of spectrum analyzer do you have Sir ??
Cracking idea, getting the best out of your 4G with a tv beam, clever sod lol :-D.
The simple dish method works well for ordinary wifi internet, but thats about 2.5ghz, so a beam would be out of the question i suppose.
I honestly just have no idea about what I'm doing, lol.
Ive just watched the "Making of" video :-), you have got an excellent connection in comparison to what you had :-D
18-20 mb per sec, i would be super happy with that :-D.
You may not know all about every aspect of antennas, but i think you did a brilliant job, im chuffed for you :-D :-D.
Thanks - Above all it makes my TH-cam uploads not kill the entire Internet connection for a day at a time. It's a lot more inspiring to make videos when their biggest impact on your life ISN'T to rob you of the 'net a couple days a week.
Yes thats why im happy for you, but dont just think about uploads, enjoy downloading as well.
I used to be on a shitty phone based internet, it was horrible, so i really do understand how you feel.
Enjoy your net :-D
zx8401ztv Heh, thanks - will do!
Hello,
If I connect my tv antenna direct to my 4g router via an sma adaptor and lmr400 cable will it work sir?
Please answer
Interesting test. How do I figure out what frequency the nearest tower uses? I don't have a spectrum analyzer, only a cheap USB SDR. Can that be used?
Sure, just download SDRSharp and point it to the nearest cell tower.
So I don't need a cell phone booster antenna ,a tv antenna works just the same correct?
Hi, I have looked the internet but unable to find answer.. my question is LMR 400 50 ohm cable is recommended for best signal reception. But it's pretty expensive cable as I need to cover about 30 ft distance. So wanted to know can we use cable used for dish tv? Will it provide similar gains?.
Now we all know where you live. Awesome!
Send me mail.
The post where I live is super expensive (like 25 euro per package), but I will see what I can do.
marek mrukwa That was mostly a joke.
Didn't get that sorry. Nice video btw
marek mrukwa It's alright - thanks!
I have a 88dbi 4g antenna hooked up on a satellite dish for my sprint Mifi 8000 through ts9 connection and I have an 40mile directional tv antenna. So what do i need to do to combine everything?
Genius, slow clap good sir
I'm honestly puzzled.....you've basically told me that an aerial receives signals....or am i receiving something different to what your outputting?
If you're still around (or to anyone who can answer this question definitively), can you tell me if I can use my TV antenna for both my TV and my cellular booster?
I need to use my cell phone as a hotspot for internet inside a metal building. Great cell connection outside the building; terrible inside.
wow, thats a really cool little antenna. i'm a big fan of antennas. haha
If that's your definition of "little", I don't want to know what you regard as "big".
FFcossag
well i live about 60 miles from any big TV transmitter, so i'd make really large antennas to get a few channels. i didnt like watching the TV, i just wanted to get more channels. haha
Rinoa Super-Genius Such are the ways of nerds. I fully understand why you would do such a thing.
FFcossag
i found getting chicken wire fence and rolling it into tubes worked really well. i also mounted a big steel grate i'd found on my uncles farm to it and those helped also. i might get back into making a giant antenna again.
Rinoa Super-Genius Are you putting effort into being more ghetto than me? ;)
Thank you!
dude think how we convert the tv cable after amplifier to sma cable... i think a filter is needed to get the LTE 5G band...
what is your ISP ?
Do you know what frequency your modem connects to cell tower?
if it is 4G or LTE they use MIMO technology.
Therefore setup your antenna dipoles one at 45° and the other at 135° degrees.
This way you will meet 4G LTE MIMO Polarisation Diversity.
Cool, thanks.
What is your ISP (internet service provider)?
Sonera. They do 800 MHz 4G.
Hmm... That transceivers position seems a bit off to me as a radio amateur... On TV antennas, the driven elements center is on the boom of the antenna, which on that stick would be right at the hinge point of the sticks antenna if it is turned in a way that it doesn't fold back over the stick.
Have you tried different positions of the stick and antenna with regard to the boom to see what gives you the most signal?
I haven't played much since my antennas are a bit worn out and I don't want to break them. I've ordered a couple of new antennas and I'll play around more once I get them.
Amazing could you do another video like this but for 5g? thanks
IIRC, you could the same with a new 4G/5G dongle.
hi can I use SMA male to connect the coaxial cable to my pocket wifi?
I think you should check out Kreosan videos for ideas related to 4G.
OK, you antenna is normally a horizontal oriented device. Have you tried turning the antenna into the vertical plane to see if it any better. I'd bet it is.
I tried that, didn't change much.
Theoretically one could shorten the directors to receive the higher bands better but with frequencies as high as 2GHz you never know.
I see little reason to do that, since I'm not trying to push WLAN.
what price do you pay for that sort of internet
About 20 € per month.
That's cool
I think I am getting a raw deal with only 15 mbps down and 1mbps up and that is on cable broadband. The fastest I can grab a file is at about 2 mbps. In all honesty that seems fast enough, but at times I wish I had faster up load
That's my land line as well (and has been for years) - ADSL, I assume?
Cable, same as for coaxial cable TV, but I don't get TV (why would I) I have not had a Telephone line hard wired to my home since 2002. The phone company keeps trying to sell me some plan and I never get a straight answer from them as if that would be a twisted pair or fiber optic, There isn't any fiber here in this area
Craig Nehring You poor sod. I'm just waiting for the new local telecom to come knocking. They've been making the rounds offering free fiber installations to new customers for a while.
I could upgrade to higher tier with cable, but they still short you on the upload speed. They are pathetic, I tried to upgrade to one of the new cable modems Docsis 3, it took the techs over an hour on their end to configure it, then the damned connection would drop out briefly a few times a day. I am running a tried and true and very old modem.
Oh BTW, I have played with some one watt wireless dongles and high gain antennas. But that is not exactly cool to be stealing service... it does work though at some distances.
Have you ever toyed around with Software Defined Radio? I think you could have scanned for the LTE signal with a RTL2832U based DVB-T dongle (10-20 euros) and your PC. If you have not toyed around with SDR yet, it is definitely worth a shot, i think it would make good content for your channel. It is amazing that part of that multiple thousand$ sewing machine sized machine you borrowed can be replaced by a super small USB PCB not even designed to do the job.
I've used those RTLSDR things in the past, they have their place. I'm not a radio guy though, so I don't find them too fascinating beyond their raw utility value. I could very well have used one of those for this if I wanted to, but I'm sure you'll agree that the Unaohm 742 is several orders of magnitude cooler, he he.
Alright, no surprise you know about those :) Yeah definitely cooler!
Nothing is better than straight frequency information to a CRT with no
digital lag!
geekmystique Ha - while it may not have digital lag, the analogue sampling system that the 742 uses is dog slow and will miss any burst that's less than 50-100 ms or so. It's not actually a very good spectrum analyser, lol.
geekmystique
I agree on that, RTL-SDR usb stick is well worth to experiment with.
If I got a 4G router/modem - could I connect it directly in?
tHERE IS IN ANY WAY THAT i CAN BUY IN USA...?
Guillermo Yanez it’s a tv antenna
Thumbs up :)
Can you take the cable from the antenna and feed into a 4g router
@Roy Mazingo check it out here www.coaxrf.com/product-category/2-rf-adapters/sma-to-f-type/
tv connector type F, so need from f head to N sma RF head, with pin is male, hole is female
@Roy Mazingo and do u know what? if tv antenna got booster/voltage and booom! got very strong signal coverage! example
www.amazon.com/dp/B07GSCCJ9Y/ref=emc_b_5_i
I believe Kreosan did something like that in one of his videos. He's the type of guy who experiments electromagnetic stuff.
is that 4g connection free?
No, of course not.
Nothing is free
Hmmm, nice work... I'm thinking you could probably use a cheap WiFi yagi for 2100MHz... Similar enough range.
How would 2,1 GHz divide down very well to 800 MHz? It doesn't add up in my head. As far as cheap goes, however - this antenna was free.
FFcossag I was thinking more of adapting your idea to my provider which uses 2.1G for 4G I believe, and I have an old 28dBi (I think) 2.4G yagi in the garage.
Ah feck, 4G uses 1800 and 2600 here... that said a 2.4G yagi should still work fairly well at 2600...
Jason james Ah, I see.
@@jasejj seems you know alot of antennas can you help me going to buy a phone booster 850 mhz. Thats for 3g right ? And also planning tu buy a yagi antenna 25dbi thats says 4g will that antenna work out with the booster just want to make sure to get more. Signal thanks
That's pretty slow internet, I hope it's not expensive
It's not - about 20 € per month. It's considerably faster when I'm closer to civilisation.
FFcossag
What ISP are you using?
how far can you control a a rc car with that antenna
I wouldn't have the slightest clue.
FFcossag brobaly really far could be a fun for a prank
Nice joke HAHAHA how could it be?🤣
paused video at start , not warching its total bs, tv is under 1ghz up to 3ghz frequency cell is above tv frequencies not possible, total nonsense. also frequencies above 1 gzh are smaller so the waveguide etc are smaller. not the long rods of a tv antenna .
4G here is 800 MHz.
Woops, you accidentally assumed that just because cell towers in YOUR country or region transmit in a certain band, that ALL regions must...
What an idiot.
Here in Australia we get as low as 700mhz in some areas, all the way up to nearly 3k in urban areas. 700-900 is generally used in rural areas.
Nice try though!
I have lte filters to prevent cell signals from interfering with the cable broadcast. I work for a major cable company and yes, lte can cause issues depending on where the home is located within the cell tower broadcast.
fake
And you're just jealous that others can boost 4G signals better than you like Kreosan.
