Product Overview

The Southwest Antennas part # 1027-002 GPS Active L1 Antenna is a high-performance and ruggedized product designed for GPS receivers, manpack, hand-held, and 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 >30 dB out of band rejection from 38 MHz above and below the L1 center frequency and >50 dB out of band rejection from 50 MHz above and below the L1 center frequency. The integrated high linearity LNA provides both a very low noise figure (<1.5dB) and a high input IP3 (+4.9 dBm).

Features: 
  • GPS L1 frequency +/- 10.23 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
  • Ultra light-weight design
  • Ruggedized design
  • 50 V/m jamming resistant
  • Burn-out protection, in band jamming
  • Ground plane independent
  • Recessed TNC male interface
  • Exceptional pattern bandwidth
  • Waterproof to 20 meters (65.6 ft.)
