Video Patch Antenna FT 2.7–2.9GHz 18.5dBi RHCP

The FT 2.7–2.9 GHz 16.5 dBi RHCP patch antenna is a directional antenna for transmitting and receiving video signals in the 2700–2900 MHz band, with a 2.8 GHz center frequency.

Its 18.5 dBi gain, combined with a narrow directional pattern, concentrates energy in the desired direction, helping extend video-link range and reduce interference from off-axis sources compared to omnidirectional antennas.

A 14° horizontal and 26° vertical beamwidth makes the antenna easier to aim at the drone and provides more stable reception at distance. RHCP circular polarization helps mitigate multipath reflections and signal dropouts as the UAV changes orientation, which is especially important for FPV systems.

The flat patch form factor is convenient for mounting on a tripod or ground-station hardware. The SMA Female connector ensures compatibility with most video receivers and video-link modules with a 50 Ω impedance, while the 400 MHz bandwidth supports stable operation across the working range.
