Wi-Sys Communications Inc. WS3910 High Gain, Low Noise GPS Antenna Applications: Automotive Navigation Fleet Management & Telematics Marine Navigation Asset Tracking Military Radio and Vehicle Law Enforcement The WS3910 GPS antenna is unparalleled in quality and performance. It features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects. This element, along with a low noise amplifier and SAW filter, enables the WS3910 to provide a consistent, clear signal while minimizing loss-of-lock if GPS conditions are less than ideal. With both a magnetic base and threaded holes for mounting screws, the WS3910 GPS antenna is ideal for vehicle mounted AVL applications. Features: High gain: 28 dB 3.3 V Extremely low noise figure: 0.8 dB Excellent out-of-band signal rejection Wide range of connector types available High performance LNA (patented) Wide voltage input range (2.7 5 VDC) Excellent low elevation angle coverage Technical Specifications Wi-Sys Communications Inc.
