Overview

The GEPRC SOMA 3.3G antenna is an Antenna designed for 3.3GHz FPV video transmission. It uses an integrated molded enclosure to help prevent signal instability caused by deformation of the RF PCB under external force, and is specified with up to 4.85 dBi gain and low SWR for use with 3.3G VTX and compatible image transmission/reception modules.

Key Features

  • Integrated molded enclosure / protective shell design to shield the PCB and improve reliability.
  • Flexible PCB solution; circularly polarized omnidirectional RF solution.
  • Omnidirectional RF design for reliable signal coverage for FPV during high-angle maneuvers.
  • Up to 4.85 dBi gain; ultra-low standing wave ratio (low VSWR / SWR).
  • Premium SMA connector for minimized VSWR and improved transmission efficiency.
  • Each antenna is tested with a spectrum analyzer to meet SWR standards.
