- This is probably the best antenna that we have looked at so far in the 3G 4G range but like most of the antennas it will work best between 1800MHz and 2200MHz. I just wish they would not exaggerate the gain!

This is probably the best antenna that we have looked at so far in the 3G 4G range. It is just a shame they have to exaggerate the gain!
looks like the one i got from ebay but my antenna is really crappy it droped my internet speed from 25Mb/ps to 6Mb/ps
Great analysis & experimentation as usual !!!
- The 'McNiel modified' antenna,... ( i.e. spoon shortened ellipse ) with the response seen ~ at time-line 15:50 ~ showing 1500Mhz - 2100Mhz is slap bang in the Dn-link ; Up-Link frequencies of UK Telephone carrier >> 3Mobile
very informative, thanks so much
"Build as per your local area frequency". My takeaway from this, another, super informative video. Thanks!
Very interesting. Just bought one, deplored being not better than built in antenna, disassembled it and then found this video
Thank you for all the videos showing us how you make different antennas and how well they work! But for someone as dumb and lazy as me, I have a request (you can consider it a challenge ;-)). Can you fashion an antenna for 2.35 Ghz out of the garden variety TV coax cable, where I could just take a long piece of coax up to my roof, strip the outer cover, expose the center conductor, twist it (not too complex, because I lack even the skills you'd consider basic) into a suitable antenna and fix the coax to something (most likely a wall) and then get back into the living room and do the same with the other end. This way, no cutting, no soldering, no special impedance matching devices (I guess it would mean coiling the center conductor suitably without any special tools) etc. And we could make the enhanced LTE signal make its way into the living room with just a length of coax and some elbow grease (and your brainwork of course!). I eagerly await the McNeil Antenna! TIA.
Also, I'm in India, so I'm not sure if I can get RG6 or RF 200 cables easily, Satellite TV cable (75 ohm I think) is readily available. This would be for Jio LTE on the following bands :
Band 3 1800MHz fdd, band 5 850MHz fdd, and Band 40 2300MHz TDD. The rooftop antenna would be directional, and the living room antenna would be omnidirectional.

No wonder it sells good. 35dB antennas are pretty hard to find, especially small ones :)
Interesting design, I never came across one like this.
What is your black test board thing with the hole grid, did you build it yourself or is it an off the shelf product?
I guess most antennas work best around 1.8GHz simply because it is the most used band in Europe, so they try to make it atleast somewhat decent in that frequency range.
I'm looking forward to see what you can do with the sector antenna elements, I sent you. :)
I did make it myself
Agreed,...

Another good video Andrew
Interesting vid, I am wondering with the design if upper frequencies become horizontally polarised?
-7db of gain could be a good thing for me... I need more but for $40 for 2 of these, I'm willing to try them.
Currently I'm at these specs---
RSRP:
-103 dBm
RSRQ:
-18 dBm
SNR:
-3 dB
Really enjoying your tear downs and experimentation. Satisfies my inner nerd.
I suspect this was a case of:
Tech Guy: "I've designed a good, simple 1.8 GHz antenna"
Marketing Guy: No! No! No! We want a wideband antenna with some gain we can boast about. Look, there's no time or budget to change the design. Put two of those in the case and we'll get more of everything and save the extra cost when our Chinese friends build it with the cheapest, crappiest materials they can find.
Can't fault your practical knowledge and experience so I'll criticise your use of terminology instead 😉.
"PCB Board" in the contexts you use it in is a tautology, essentially comes out as "printed circuit board board". "PCB" or "PC Board".
"Stripline" When implemented in a PCB, you can't usually see the signal feed line as it's hidden between two planes, the whole being a three-layer structure. So this antenna is not fed by a stripline.
The subject antenna employed a simple "microstrip" feed comprising a two-layer board with one signal layer and one plane layer. You improved this with extra copper tape grounds to turn the simple microstrip into a "co-planar microstrip".
I've spent too much time using software like Polar creating these things.
Awesome! Can you try the parabolic dish anttena for LTE? The mimo one.
Yes please do a video on parabolic LTE antenna.
It is on the list
@@andrewmcneil Thank you very much. I'm desperately waiting for that video. Keep it up the Good work :)
What LTE antenna would you recommend. Looking for a good 4G/5G LTE antenna to hookup to my lte router through tmobile USA.
Did you contact waveform ?
Perfect DECT Antenna
This is really good with a satellite dish . Maybe with a large dish you can get around that gain .
Very interesting video. I do hope you will be looking at some more of these 4G LTE antennas.
That's the plan!
@@andrewmcneil Righty-oh. Looking forward to those.
There is something i cant understand. when you show the results from the network analyzer you cant know precisely the gain of the antena at a certain frequency?
thanks.
Great video thanks I'm glad I didn't get one of these. Now what would be the best antenna to make or buy for the 800MHz range. As that is what Vodafone it using in my area and would be great for my 4g LTE router
Sorry, why don't you post the dimensions?
Sir i m an old subscriber of u..i meed biquad design for 1800 nd 850 lte bands..i m from a village and need good antenna..i bought alots..but thy dnt work as promised
You only tested one connector on the analyzer?
Good job sir .......................................
The mid 3ghz was where my wimax was tuned to
Thank U Andrew..^_^.Learn more from U
My pleasure!
Hi, Andrew! Is it possible to modify an LNB device to work as a wifi cantenna pointing towards a satellite dish?
Unfortunately not
@@andrewmcneil Thanks for replying. I just want to clarify that I didn't mean to mod the LNB internal components to transmit/receive WiFi signal but to just use its body as a horn cantannea.
@@adelkhalifa1104 Just use Canntena Anstead of the LNB
Where can i find best antenna for 2500-2600MHz?
Did you contact waveform ?
What are the specs/type of your directional coupler?
This one is good up to 3.5GHz
next time can you use a better camera???
You can buy a camera and ship to him.
it might work with the TECHNICS ST-GT1000, A Slim-Jim antenna for 900-2304MHZ might worth trying.
Great video.....thanks....:)
You're welcome!
TRISTE VI MUITAS MENSAGENS DIZENDO QUE ERA UMA ANTENA TOP MAS DA PRA DESCONFIAR
Top antenna 🤣🤣🤣🤣🤣🤣
At 15:50 you said 1.4Mhz to 2.3Ghz.
I think you meant 1.4Ghz.
I do
❤️🌹
Hello, not omnidirectional and 35 db gain unbelievable.
35dbi……🤣
what is the name of that good antenna
