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 Trip…

FPV is made possible thanks to two RF links, a control link, and a video link. Without an RF Power Meter, a pilot has no way to test these critical RF links. Test equipment for microwave (GHz) links is not cheap. ImmersionRC changed this several years ago and provided their ‘Power Meter v1’ to the FPV community. The v2 is the result of listening to customer feedback. ImmersionRC added an internal battery, an internal attenuator, and other features that every FPVer needs. Accurate RF Power Meas…
