The FPV Triple Feed Patch antenna is a directional circularly polarized antenna. The connector type is SMA Male to SMA Male. Note: This antenna is not included a terminator. 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. With Adapter Link: FS-GR3E. Package included: 1 x Triple Feed Patch Antenna, 1 x semi-rigid coax (SMA male to SMA male). If there is any problem please contact us feel free.
