## **Wi-Sys Communications Inc. WS3911-HR** “No Interference” GPS Antenna with Dual SAW High Rejection Filter 

## **Applications:** 

- ♦ Anti-jam / Mission Critical GPS 

- ♦ Military Radios and Vehicles 

- ♦ Law Enforcement / Public Safety 

- ♦ Avionics 

- ♦ Fleet Management & Telematics ♦ Asset Tracking 

The WS3911-HR “No Interference” GPS Antenna with Dual SAW High Rejection Filter has the industry’s best out-of-band filter performance.  The WS3911-HR features ESD circuit protection, a patented two-stage low noise amplifier and a dual SAW high rejection filter.  It also features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects. The WS3911-HR provides the most consistent, clear GPS signal reception while minimizing loss-oflock in high-RF fields.  Housed in a weatherproof magnetic or screw mount enclosure, the WS3911HP GPS antenna is ideal for most demanding vehicle mounted GPS applications.
