Description
- weight: 485 g
Note:Terminator is not included,you can purchase it separately,click here
The Triple Feed Patch antenna is a directional circularly polarized antenna
Good radiation efficiency. Most FR4-based patches have terrible efficiency because FR4 is very lossy at 5.8 GHz.
Good axial ratio, not just directly perpendicular to the patch but also off-center.

С регионального склада доставлен IML за три дня. Упаковки и товар не повреждены. Патч хорошего качества, диски параллельны друг другу, риски совпадают, в комплекте есть переходник sma-rp-sma (накручен на соединительный кабель, который хорошо гнется и фиксируется в выбранном положении). Доволен приобретением.

сСпаяно и собрано очень хорошо. Удобно упаковано к пластиковый кейс. Брал вместо родного патча в ev800d И ev800dm.

Better than Eachine Stingpad on Ev800D

This antenna is working very well and has very good build quality.
Works very well on my google. Increase the video transmission quality
Excellent directional antenna that can be used both as rhcp and lhcp. For optimal performance you will also need 50 ohm terminator that is not included in the package.

I think this is great. Great range, good video signal.

Just wish they included a terminator instead of the SMA to RP-SMA

I got black version, 2x units. I usually do and tune all my antennas myself, but this time decided to test what we can get for cheap ;-)
Looks like they used wrong PCB material or mixed something with dimensions - antennas are usable for lower 5.8G frequency range (5600-5750 or smth), going higher - one antenna is barely usable (usually on such "patch-type" antennas axial ratio is very bad, when you go out of resonant frequency), another is unusable at all.
So, if you fly on smth like C4 (5705) or something this should be fine. But for higher frequencies...
Actually, fixing "too high" resonant frequency is easy - just put some lacquer/paint, this would shift frequencies down, but with "too low" - not much you can do except cutting/sanding boards which is really time consuming.
