5.8GHz Triple Feed Patch Antenna for FPV Goggle Eachine EV800D EV200D EV100 VR006 for FatShark HDO HD3 long range sma load 

Features:

The FPV Triple Feed Patch antenna is a directional circularly polarized antenna with powerful signal. Connector type is SMA Male to SMA Male. 

 It can be used as LHCP or RHCP antenna, so it's very versatile.

A 50ohm dummy load terminator is included which can achieve best signal. 

Suit for FPV google like Eachine EV800D EV200D EV100 VR006, ect.  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.

Cheap and easy to manufacture with high accuracy, even for a hobbyist.
