Wi-Sys Communications Inc. WS3997 Low Profile Surface Mount GPS Antenna Applications: Permanent Surface Mount Vehicle Installations Fleet Management & Telematics Marine Vessel Installations Cellular Base Station Clocking and Timing WiMAX & Fixed Wireless Broadband Clocking and Timing The WS3997 surface mount GPS Antenna provides very high performance in a very small form factor. It features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent obje cts. This element, along with a low noise amplifier and SAW filter, enables the WS3997 to provide a co nsistent, clear signal while minimizing loss-of-lock when GPS conditions are less than ideal. The WS3997 is housed in a very compact all-plastic, non-corrosive low profile package. Designed for permanent mount installations, the WS3997s thru surface connector provides the lowest in-vehicle profile. Truly is the optimum choice for dependable, clear and consistent GPS signal reception. The WS3997 comes with a MCX jack connector, and a flying cable option is also available.
