The GPS Antennas – Model 7131 is an external, high performance Global Positioning System (GPS) antenna for use with the ALERT2 family of Data Transmitters. The low profile permanent mount GPS antennas provide 28 dB gain and superior out-of-band rejection performance and is the optimum choice for GPS tracking and timing applications with high radio frequency fields. The GPS Antennas feature a precision tuned custom ceramic patch element for maximum signal reception, 15KV ESD circuit protection, a 3 stage low noise amplifier (LNA) circuit and dual high rejection surface acoustic wave (SAW) filters. This enables the GPS Antenna to provide a reliable and clear GPS signal while minimizing loss-of-lock, even when conditions are less than ideal.
The GPS Antennas deliver high-gain, low-noise performance in a rugged and compact package. It features a wide operation temperature, wide operating voltage, and low current consumption.
