Fantastic! let us know how you get on

@@andrewmcneil my man came trough once more with a 5g antenna this is why i subbed

@@andrewmcneil dear Andrew does bigger mean better when it comes to 5g to Tower is within line of sight only about a kilometer or 3 away. My monkey brain looks at this and thinks it's too Small to work

@@andrewmcneil Hi Sir. This DIY 5G antenna is better than a 5G Yagi-Uda antenna from Cantenna app in android? Want to know if you deployed and test the antenna in outdoor with your modem. How was the signals?

Sooo.. Did you make one? How did it go?

Thank you! Cheers!

What router are you using?

It is just options I do have a 5G mast quite close to my home.

5G is particularly bad at penetrating buildings, given such a high frequency. I built these because I can't very well stick my gateway with internal receivers out in the rain, but this can sit nicely atop a short mast on the roof.

Well 4G gives me about 1.2 MBit/sec evening time (not great, practically useless) and 5G runs on about 40 MBit/sec but if I close the window the 5G dissapears. Im on a loft and I can clearly see the 2 5G masts. One is about half kilometer the other is 300 meters away. It was all fine from spring to this point in time even with closed windows or even behind a wall. About 3 days ago everything changed so I have to make some external antenna for my CPE pro 2 which doesnt even has an external antenna connector... :(

@@JohnSmith-xz5nb 300m should work fine...

I have nearly 4.5 km to the 5G tower and I can get 400 mb/s. And antenna should make a big difference.

0.5 😁

I was wondering the exact same...

Nice

@@andrewmcneil I can't find a way to place a picture here on what I made but they are 150mm apart and sitting on mini tripod. Also material used for is not brass.

Great success! Really thinking of making this type of antennas considering the price tag of commercial ones. Where did you get the brass sheets? I am also in UK, in London. How did you attached them to achieve MIMO effect?

Congrats, I just building one for myself to work with huawei cpe router (attached to main port, div port not plugged), unfortunately something went wrong, and it's not working at all :|. My issue is that my router don't see 5g network when indoor, when I put it outside the window it works great, it seems that glass is impenetrable barrier for 5g signal. The idea was to put the antenna outside through the gap in the window (connected via aprox. 2m length cable / 2mm diameter). Does you setup works with single antenna or is it required to use 2 ?

Oh great stuff! I wanted to build one too I didn't get past the eBay stage! Could you link where you got your materials from by any chance? I was looking but I was getting nowhere and I gave up. I'm Also in the UK! You are a total legend 🙏

I used to make longer videos explaining a lot of this but people complained I talked too much. I do plan to make a more general video explaining how the measurements work like this with panel antennas.

Superb video Andrew thanks... I'd like to build an higher gain LTE+ antenna to work with 2600mhz in a 4x4 Mimo arrangement. What changes would be needed to adapt an antenna like this? Regards Andy

@@andrewmcneil your knowledge is invaluable, you don't talk too much. In a sea of falsely advertised e-junk destined sadly for landfill you provide help and solutions. Now you've built this though I would love to see you put it through your normal tests on the scope etc.

Just about to do exactly the same... I am on the very fringes of 5g. The router is a 4g5g MIMO... So i need to build 4 😂

@@G-Cam1 How is success with an antenna? I want to do the same for my M801A router from Three

did you do this? what were your results like?

How did you go mate? ​@G-Cam1

sounds like you need something like a Yagi

Thanks and welcome

@@andrewmcneil sir i have one question plz, can i use it as parabolic feed ? On grid or dish if yes what will be the approximate gain? Thanks 🙏

@@devgiri8613 yes you can as for the gain that will depend on the size of the dish

@@andrewmcneil Thank you sir 🙏

Thank you, I will

No

Correction: I realized that your frequencies are 3.3Ghz - 3.8Ghz. So my scaling should be .6133? So 18mm diameter would change to 11mm for me.

I would like to know this too

Sir???

Yes you can and yes a dish would

It is yes

directional

No thats not how antennas work sorry

@@andrewmcneil OK I thought so, now this leads me to another question. How would one go about making this into a 4X4 MIMO Antenna Array? I know I will need 4 of them but what about spacing between each antenna? What would the spacing need to be between antennas side by side, I.E, 2 on top and 2 bellow, like a 4 on a dice, for a 4X4 MIMO antenna array? Hoping you can answer this or make a video on the topic as you are the antenna GURU

Tất nhiên là hoạt động rồi 4g tần số 900 mhz không ổn định nên mình cũng làm 2 cái cho mr200

rg402

@@andrewmcneil Thanks for that. I have ordered it from AliExpress and tried it out and it solders great! But I'm not getting the results I was hoping for. I may be a little confused about the capabilities... I have stripped about .5m of the other end of the cable, bent it into a flat radiating rectangle pattern (like in that crazy Russian wifi gun video) and put my iPhone on it to get some gain. It's not working. I'm surely not doing it right... Do I need a powered 5g modem? How would I make a "cradle" for a phone? Any pointers?

yes

For the basic starting size this: www.everythingrf.com/rf-calculators/microstrip-patch-antenna-calculator

@@andrewmcneil - Big thanks Andrew,.... I ask, because I would like to compare the calculator with my own numbers... to see where I may be leaving out any 'factors'. .

@@stevemacbr No problem the biggest factors or the dielectric constant and the thickness of the dielectric. It is interesting to see how some materials can have a huge effect of the measurements.

@@andrewmcneil - Exactly. I own a PS100 Vextor Analyser,... and a LCR analyser,... so these give me a clue to the direction I need to go in. - Many thanks for sharing our experience and practical - no nonsense builds.

Yes 👍👍

Same size more parasitic elements

It would probably effect the function of it at other frequencies but you can do the math to make one it just will have very different characteriristics.

0.5mm

You can solder to bare aluminum with tin/lead solder. However, the problem is that aluminum oxidizes so easily and solder won't stick to aluminum oxide. You need to clean down to bare aluminum and then somehow keep any oxygen from getting to the aluminum while you heat it. There are special aluminum soldering fluxes you can get, or some people say to coat the aluminum with oil before heating. Another technique(the one I use) is to build up a puddle of solder on the aluminum. The aluminum oxidizes under the puddle so it doesn't stick, but while still heating, use a sharp probe or sharp soldering tip to scrape away the oxidation under the puddle. The solder puddle will roll around on flat aluminum oxide layer so I often press a small dimple in the aluminum to keep it in place until I scrape away the oxidation.

none

I'm sorry I don't understand. Can I use normal steel bolt and nuts there?

Or should I go with some non conducting material like plastic??

@@swapnilsuryawanshi4519 Use nylon non conductive

Thank you

you should try the sleeve monopole antenna with cantenna, I also make it but the problem is 1.8, 2.3, 2.5Ghz band is slow at my place so I need a 700mhz antenna because it's the only one that have good speed👌👍

Next video is a dish feed for 5G but I also have a 4G on the way

They are 40 grit sanding belts that I cut up

No it does not work like that

@@andrewmcneil Thanks. I thought it could be built like the "5GHz Wifi Antenna with 15dbI of Gain"

bump

LoL yes 0.5mm I had to render this twice because I corrupted the first time and I still did not spot that.

Yep

@@andrewmcneil I'd be really interested to see if they do any better at 3.4ghz vs your 5G antenna you made a few videos ago. My huawei cpe pro has separate 5G 4x4 mimo and 4G 4x4 mimo antenna ports so seems a bit mad to fit a wideband (xpol) antenna when it's only going to be used at 3.4ghz

No, it’s an isolated design

​@@andrewmcneil if we use iron metal rod, then it becomes all rings shorted. Then it works???

@@MovieKING-eq5qw no it will change the center frequency

You would need to experiment running speed tests as there is not set distance. It depends on your distance from the tower.

@@grandpaseed No I have been working on version 2 but I have been too busy.

Hi no it is a patch antenna with parasitic elements

Yes but I have not made any 5.8GHz antennas for some time

@@andrewmcneil I diy flycam , so I need antenna 433, 2.4 and 5.8

I’m gonna try to make one in a month. Will let you know bow it works on ZTE Router. Biggest problem might be fitting both antennas next to each other.

There is in the discription

I can but people want me to make a 4G biquad first

Nylon

I imagine it would depend on how close you are to the nearest mast/the signal coverage in your area?

yes, please confirm thickness; 5mm seems unlikely!

Yes I did

@@andrewmcneil great thanks

@@andrewmcneil thanks Andrew! - I hope to open my Vodafone router to connect external antennas; it will invalidate my warranty, anyone done this (I do not have external antenna connections)

@@jtreg I want to start and get some of these routers in and modify them but the layout inside would probably be the same as a wifi router

It’s a patch antenna with parasitic elements that operate in the same way as a Yagi to narrow the beamwidth increasing gain

​@andrew mcneil totally found it thank you! I had no idea it was that easy

No, a patch antenna with parisitic elements

@@andrewmcneil ok sir thank you 🤩

@@andrewmcneil sir instead of nylon... Can we use abs or pla??

I do 😁😁

I like working with it and it looks nice

@@andrewmcneilUsing some other conductors affects the gain of the antenna ?

@@divyamohan8442 Not at this level, yes copper is a better conductor than aluminium and silver is a better conductor than copper. But to try and measure the difference in the performance of an antenna you would need some very expensive equipment. And in the real world of what we use them for it would not make any difference. In fact, if you go into any professional RF lab you would find most of their reference antennas are made from brass. Reason being it is more durable and harder than copper and does not tarnish like copper.

just don't use lead 😁

@@andrewmcneil Thankyou Sir

LOL 0.5

@@andrewmcneil Sir, thank you so much for your response. Any chance I can ask another quick question? I have a *ZTE* MC801A. Both TS9 ports are really close to each other. From your experience, what would be the best way to make 2 antennas that will not be colliding with each other?

No sorry
