Oh well, what a classic. I had some of this coax as well, it's a waste of connectors - atleast as a transmission line. It does however make a good attenuator or floor heater at higher power. Right after seing a F-connector on some 50Ohm coax, the case was clear. ;) The antenna is pretty nice however, I got the same one, with decent coax and some minor fixes, it performs nicely. As you said, for the amount of money, that these cost, it is hard to get it built yourself.
I need a 2100mhz antenna. Actually i will try to build a double biquad antenna but if I fail i have to buy a working antenna. I will use 8 meters long lmr 400 coax for double biquad antenna. Reflector is 1.2mm thick galvanized sheet. Copper wire is 1.5mm thick. Could you please give me a link for correct dimensions for d-biquad antenna? I already made some research but i got confused about dimensions.
I want to make lpda antenna with 64cm boom length aluminium. Could you please guide me little bit. How many wings and maximum and minimum length of wings should I have to used for my wifi router
Good video. I have two questions what is that antenna you puled out @ 7:40 in the video and did you make a video about it? Also did you finish your Cantenna Book?
Hello, I have just purchased a Cell Phone booster that came with this almost identical antenna. My question is why would they send this antenna when the booster is for 850MHz Band 5, 1700/2100MHz Band 4 and 1900MHz Band 5. Am I missing something?
It would be fine for 850 due to it being a Yagi (broadband) but forget 17, 19 and 21. Look for a 3g, 4g multiband Yagi on ebay you will find one for around £20 to £30.
Quite often in his videos McNeil demonstrates that apparently he does not understand the basics, which is a shame because he could quite easily measure the gain of his antennas in dB over a reference dipole or whatever, but instead only ever gives us an un-referenced 'percentage' figure.
@@stephenstebbing9460 Yes, he has all the necessary test gear, but doesn't make best use of it. And counting the amount of access points he can see, as a measure of antenna gain, is flawed too. An antenna's gain is achieved by tightly focussing its directional characteristics, so under certain conditions, more access points received could actually point to an antenna with a LOWER gain. That 900MHz antenna with its interesting balun arrangement seems quite good; I suspect the poor coax was someone else's addition - possibly 75 ohm satellite type, where high losses are acceptable due to the extreme gain in the dish's LNB.
Very useful Video. Thanks Andrew.
Glad it was helpful!

LMR600 COAX is what is required.
Good job sir ...keep it ...
Thank you, I will
Very nice review.What can I do to make it resonate at 868Mhz..? Thanks!
Add some RG213 coax
Can you provide a link to the antenna? I might be interested in it, bearing in mind I'll have to use my own LMR400 with it.
Andrew, how would this antenna work for the helium network in the USA, thx

Hi, does anyone know what is the impedance of this antenna with this internal balun configuration?
Good video. I have two questions what is that antenna you puled out @ 7:40 in the video and did you make a video about it? Also did you finish your Cantenna Book?
@7:40 search Yagi antenna on my channel from 2 years ago. As for the book no it is 90% finished
Thanks
No problem
It would be nice to see the amplifier they supply tested
Friday
The Antenna might have been for the 928MHZ UHF CB Radio System that is no longer legal.
Would really have liked to see what had happened when you connected good coax to it.

is this compitable as an nantenna in zlt tozed s10g modem?? pls
Hey did anyone try a cantenna with 2 monopole elements inside ( vertical and horizontal ) for LTE MIMO ?? ( maybe with satellite dish )
I have never tried it.

10:25 When you lose 8dB that's not a half :-), you lose 5/6 of output power.

Junky coax so many times. :(
