Product Overview

The Southwest Antennas part # 1027-018 GPS Active L1 Antenna is a high-performance and ruggedized product designed to provide accurate timing and location services for GPS receivers, manpack radios, hand-held tactical radio systems, and other small form factor radio systems.

The GPS L1 Active Antenna features +11 dB of active low noise amplifier gain coupled with narrowband SAW filtering providing >40 dB out of band rejection from 35MHz above and below the L1 center frequency. The integrated high linearity LNA provides both a very low noise figure (<2.3 dB) and a high output IP3 (+15 dBm).

Features: 
  • GPS L1 frequency +/- 20 MHz bandwidth
  • Out-of-band jamming immunity
  • Superior out of band rejection
  • Ultra low noise figure
  • Ultra low power consumption
  • Active LNA & Dual SAW filter circuitry
  • Small form factor, light-weight
  • Ruggedized design
  • 50 V/m jamming resistant
  • Burn-out protection, in-band jamming
  • Ground plane independent
  • Recessed TNC(m) RF connector
  • Exceptional pattern bandwidth
  • Waterproof to 20 meters (65.6 ft.) when mated
