Product Overview

Southwest Antennas part # 1027-020 is a small form factor GPS Passive L1 antenna which can be deployed for accurate timing and location services on GPS receivers, manpack radios, hand-held tactical radio systems, and other small form factor radio systems.

The small size and light weight design of this rugged, high-performance GPS antenna versus similar GPS Passive antennas make it ideal for unmanned system, autonomous vehicles, and other automated or remote assets where antenna size needs to be minimized.

Features: 
  • GPS L1 frequency +/- 10.23 MHz bandwidth
  • Exceptional pattern bandwidth
  • Small form factor, light-weight design: 0.5 oz
  • Ruggedized design
  • Ground plane independent
  • Recessed non-rotating SMA(m) RF connector
  • Waterproof to 20 meters (65.6 ft.) when mated
