RCmall 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.

Made it to the top of the Empire State at 400mw The sma coax adapter is just as clutch as the Antenna.

I am using this patch antenna with my HDZERO goggles for analog. Works great. Only minor complaint is the antenna if fairly large. May also be why is works so well!

This is "THE" antenna developed by Maarten Baert and Robin Theunis. If you don't know what all the fuss is about I highly suggest doing a search on "Triple Feed Antenna Maarten Baert". You will come to his official website and learn about this specific antenna and how to works and how you can use it with FPV goggles. My first version of this exact antenna I had to pay someone to make it for me, and I still had to purchase the terminator and cables separately. However, this one comes fully pre-built with terminator and cable included! For the price it can't be beat, and yes this is based on Maarten Baert and Robin Theunis opensource triple feed antenna and works just as it should. It has a much higher axial ratio than most other FR4 based Patch antenna and the design is about 7 years old, but hey no need to fix something that works so well. Use as either RHCP or LHCP but not both. Works as intended, well made, and comes in sealed in a static free bag. Makes an awesome gift for that FPV enthusiast.
