Wi-Sys Communications Inc. WS3914 Low Current GPS Antenna Applications: Automotive Navigation Fleet Management & Telematics Marine Navigation Asset Tracking Military Radio and Vehicle Law Enforcement The WS3914 GPS antenna uses the same advanced circuitry as our high performance WS3910 antenna, redesigned to operate on only 2 mA of current setting a new standard for the industry. Performance is not sacrificed the antenna still features a custom designed ceramic patch element along with a patented low noise amplifier and SAW filter, enabling the WS3914 to provide a consistent, clear signal while minimizing loss-of-lock. The WS3914 antenna is ideal for portable applications where low power operation is a necessity. Features: Extremely low current: 2 mA 2.7 VDC Very low noise figure: 1 dB Excellent out-of-band signal rejection High performance patented LNA Wide range of connector types available Wide voltage input range (2.5 3.3 VDC) Wi-Sys Communications Inc.
