GPS Active L1 Antenna, +11 dB Active Gain, SMA(m)
Product Overview
The Southwest Antennas part # 1027-004 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 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 (<1.5 dB) and a high input IP3 (+4.9 dBm).
