Product Overview

The Southwest Antennas part # 1027-026 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 (<2.2 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
