GEPRC SOMA 3.3G RHCP SMA Antenna (170mm)

The GEPRC SOMA 3.3G is a 170 mm omnidirectional RHCP antenna with an SMA connector for 3.3 GHz FPV video links. Its FPC + PCB radiating element sits inside a moulded ABS enclosure that stops it deforming in knocks and crashes, making it a sturdy choice for goggles and ground receivers on the 3.3 GHz band.

Key features

• 4.85 dBi gain across a 3.0-3.5 GHz band, centred on 3.3 GHz
• SWR of 1.44 or lower with 85% radiation efficiency
• Axial ratio of 3 or lower and -25 dB cross-polarisation suppression for clean circular polarisation
• Protective ABS enclosure around the FPC + PCB element
• Each antenna is SWR-tested against GEPRC's specification

Match it to the rest of your link: run RHCP antennas on both the transmitter and the receiver, and confirm your device uses SMA rather than RP-SMA before ordering. It covers the 3.3 GHz band only, so it will not suit 5.8 GHz or 1.2 GHz video gear.
