GEPRC SOMA 1.2G/1.3G Antenna (Omnidirectional RHCP) Flexible PCB, SMA Connector, 170mm, 2 dBi

Overview

The GEPRC SOMA 1.2G/1.3G Antenna is an omnidirectional antenna built with a flexible PCB material and circular polarization (RHCP) for wide signal coverage and stable signal integrity during wide-angle maneuvers. It is designed with a two-bandwidth approach for increased gain (up to 2 dBi) and strong cross-polarization suppression to help minimize interference, including in strong electromagnetic environments.

Key Features

• Two bandwidth designs for increased gain: 1.2G band and 1.3G band options
• Flexible PCB solution; antenna design: FPC+PCB
• Omni-directional RF design for extensive signal coverage
• Ultra-low VSWR design concept; each antenna is tested with a spectrum analyzer to meet SWR standards
• Premium coaxial cable: RG141 coaxial cable with durable plastic casing
• Premium low-loss SMA connector (SMA) to help reduce loss and support lower VSWR / higher gain
