REALACC Triple Feed Patch-1 Antenna – 5.8GHz 9.4dBi Circular Polarized Directional FPV Antenna for Goggles

Description

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.
