- I make my own homemade YAGI antenna. And it works better than the factory supplied antennas.
YAGI is a directional antenna that can radiate and receive signals to/from one main direction.
MiMo (Multiple-In Multiple-Out) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation.
In this video, I show my Yagi MiMo antenna that I created from these parts.
2 x Yagi 4G Antenna : amzn.to/3ELEJlH
2 x 4G Antenna SMA Extension Cable 3 meter : amzn.to/31PXLZK
L Shaped TV Aerial Mast Pole & Bracket : amzn.to/3EQLnHy
My Yagi MiMo antenna, works better than the supplied rabbit ears that come with the MR600.

Glad you came to the realization that you didn't need to be "line of sight" to a tower to use a directional antenna. I watched your other video from 8 months ago and was reading through the comments before commenting, line of sight is not necessary for using directional antennas. Think about it... if you needed line of sight, you wouldn't have gotten a signal with an omni. Line of sight becomes an issue when you get into microwaves (2.4GHz) because the wavelength (12.49cm) is the same size as the leaves on the trees and the signal is attenuated by the leaves because they contain water. Water is a horrible conductor and absorbs microwaves. This is also why you get rain fade on satellite TV which uses the Ku frequency band (12 Ghz - 2.49cm).
Also, that omni you tried was cheap Chinese mislabeled junk. Any time an antenna says it does 2 frequencies so far apart, it can't be good at either. i.e 900mhz & 2.4Ghz
Thanks for sharing, and though I am but a complete novice at all this stuff, necessity has forced me to rapidly learn as much as a I can.
I suspect that the rabbit ear numbers being 'better' but with poorer performance is due to them picking up a 'better' placed cell tower but with poorer download capability.
Here in Mid Wales valleys, I have put up with my poor download speeds (3-5mbits) for over 12 months, because the few houses within a 5 mile radius all fair worse (many with no signal at all)
I had suspected for a long time that the tower the router was using was down the valley somewhere and the signal bouncing off hills.
I tried a Poynting Omni antenna but with little to no help
I went back to the rabbit ears with the router on the one bedroom window board that had reception.
After a few months of frustrating slow speeds again, I purchased the Poynting directional 4g A0002. With little understanding, I simply kept moving the antenna direction etc till I saw improvements (5-8mbits). I then bought the Huawei B535 with 4g+ capability ..and again saw some improvements (7-10mbits)
However, using cellmapper and heywhatsthatpath, I actually found that there are 3 possible towers with a clear line of sight (nearest being 12km and furthest 25km)
Using speed test app, I could identify which tower was being used.
I actually rode out to the tower the TPLink was connecting to for the last year and when sat within metres of the thing the download speeds on on my Samsung S20 were pretty abysmal
So then I looked for any towers I can see down the valley on all the UK networks and bought 1 month data sims to test them (EE, 02, Vodafone, 3)
What I found was that the RSRP numbers etc do not always match the actual download performance.
To sum up, Vodafones tower that is nearly 16 miles away and has terrible RSRP numbers etc, but 3 times the download speeds.
The performance gains are noticeable in all uses, whether streaming BBC iplayer, Netflix et al, or just general browsing.
I am now considering the procurement of Poyntings LPDA antenna,
When you read the information for the antennas you could buy th3 ones you showed pictures of it said the antennas should be roughly 60cm apart, that is certainly a lot closer than 60cm. Perhaps has something to do with those values being poor. I don't know anything about antennas btw.
Very good video explaining a lot , how can you have mimo down one cable some say they are but have one cable
Good videos, trying the various options and you got a good result well done.
Thanks for the video and the tests! It comes weird to me as you mentioned not being in the LOS area, so omnidirectional (OD) is supposed to be good in this case. However, since this OD is 12dBI only, it could have been more helpful. In contrast, the YAGI-type is the best choice, considering knowing at least the approximate location of the Telecom tower.
It would also be interesting to compare an LPDA-type antenna vs. YAGI regarding their working parameters.
A quick search on YAGI v LPDA suggests that LPDA is better. With these things, you have to try it to really know for sure. But I will try a LPDA next time I want to set this up. Although, my home made YAGI works very well already.
This video is Pretty cool
I intend to follow your lead and I'm going to buy those antenna, I'll let you know the results 😉🖖
Thank you for your videos !
Liar
Blimey, I wish my speeds were so slow :-(
Thanks for sharing this stuff, will investigate further.
Mid Wales, rural UK, in the valleys, no clear line of sight, a single cell mast signal bouncing up the valley (i assume), results in 3-5Mbs normal hours and 15-20Mbs unsocialable hours.
Only a single spot in the house provides the above.
Within the 2 acres of land and a Poynting directional antenna on a hieght variable pole and the modem in tow (so not a feasible option for day to day wet Wales) I can sometimes see 30mbs, but I dont think the Poynting makes that much difference for me.
I suspect that the the current location for the tplink modem is about as good as it gets except for the glass.
I'll try this sort of design from Amazon but my hopes are not high.
good luck with the new antenna you get. leave a comment if its better. I'm still using this antenna I show in the video and works well.
Love it ❤. Thx
Now the six million dollar question, how do you know the MR600 is in the MIMO mode (this is negotiated between the cell tower and the modem). I too have a MR600 V2 model and can select my bands .... cheers Paul
Interesting, so rsrp doesn't necessarily represent what speeds you will get, my rsrp is in the low 80's and 70's as well so I just assumed my limitation is the congestion (or over selling) of the tower. Do you know if your ping is consistently lower also?
hi sir do you know EAP225 TP-LINK outdoor wifi what type of antenna using? On your video i never hear you busy talking about RP-SMA that build in yagi 2 ,4ghz
Is there any point in using cross polarised antennae when connecting to the mobile network base station?
I mean, base station's signal polarisation won't change very often, you find a right one and go with it, right?
Or am I missing something?
You want MIMO configuration, which is polarized.
Hi are you in the UK? Are these directional? Did you have to point it towards the nearest mast?
Its better if you do point it directly. But since its inside the roof, the signal is bouncing everywhere so it's more unpredictable. You just try it out.
@@sbcode thanks for reply have the speeds been stable?
Late afternoons become congested on all networks. EE is the best network, but pricey. I used it for 2 years and it was adequate. th-cam.com/video/H58fxea2kaA/w-d-xo.html
What happens if you only use one of them? is that working and is it working as good as two?
you can try. It might work ok. For me its better using two.
Then you wont have MIMO, which can have a huge hit on performance
Is in your opinion worth buying these if I already get an avg of 50-60 mbps (around 100-130mbps at night) down and 40-50 mbps up? I have a really clear line of sight, about 2km away.
if it aint broke dont fix it
Have you ever tried these antennas on 5g?
No
Hello..how far away are you from cell tower? I am getting about 25 mbps download on average, but early in the morning it goes up to 80mbps. My connection is lte.
~1.5 km. My bandwidth is better in early morning hours also. Less competition.
My case is similar to yours.. I am 2km away. Outside signal strength is strong but inside poor. I think i will stick to the yagi antenna.
Range?
Sorry, i didn’t test the range
@@sbcode ok, range in the video? I have 100m range and 2 walls. I can connect with standard antenna but it's not good quality.
I don’t know. All i care is it works. And it did.
