5.8GHz Triple Feed Patch Antenna, High Gain 9.4dBi Directional Circularly Polarized LHCP RHCP Antenna with 50ohm SMA Load Terminator for FPV Racing Drone Eachine EC800D

This Triple Feed Patch Antenna, works to perfection and because the creators made it open source others can make it at a fraction of the cost... I use this antenna on my Cobra X goggles and it works to perfection with my double circular polarized antenna... I would recommend, Amazon Prime gave me next day delivery service...

Noticeable directional signal improvement! Using 1 of these on my Goggles X .. when facing the antenna towards the drone I was getting more stable signal, when I turned away signal was going out. I will be getting a second one of these! The included SMA adapter and dummy load are essential in my case! 4 stars just because the style of this antenna - with the SMA extender being the support/mount, sometimes allows the antenna to to come loose and rotate down/away from the intended direction. Maybe that is just the difference with a $15 vs $50 antenna though ¯\_(ツ)_/¯

This patch antenna works like expected and the reception is clean and definitely increased my range by at least 200m

I love these things. Excellent performance at a great price. We already look silly wearing goggles, a patch antenna hanging off the side isn't going to make it any worse - might as well have great video.

I used this on a standard (cheap) set of goggles with two antenna inputs but just one actual receiver, and a goggle with diversity receiver. In both cases, signal was no better than using the normal linear polarized "black stick" antenna that came with the goggles. This patch is also cumbersome, delicate and otherwise unwieldy. Ended up returning. Still looking.
