This 5.8GHz Right-Hand (RHCP) Circular Polarized patch antenna was custom-designed, with no expense spared, for the FPV market. Light enough to be mounted directly onto an LCD headset, or directly onto the front of a Uno or Duo receiver. Precision manufactured with very tight tolerances, each antenna is 100% tested on a professional antenna tester (Rhode & Schwartz) to ensure maximum range and performance.
