WS3947 GPS/Cell/3G/2.4 GHz Combined Covert/Dash or Glass Mount Antenna

The WS3947 GPS, Quad Cellular, 3G & 2.4 GHz ISM Band antenna is an excellent choice for Telematics systems requiring dependable and highly accurate positioning data, as well as clear and consistent host-to-vehicle communications via Quad band Cellular, 3G or 2.4 GHz ISM Band such as WiFi. The WS3947's GPS antenna portion has excellent LHCP rejection for less multi-path effects, and it includes a low noise amplifier and a narrow band SAW filter, to provide a consistent and clear GPS signal while minimizing loss-of-lock when GPS conditions are less than ideal. The Quad Cell/3G/2.4 GHz antenna portion is tuned to receive 824-894 MHz (cell), 890-960 MHz (GSM), 1710-1880 MHz (European), and 1850-1990 MHz (N. American), as well as 1885-2200 MHz (US & Euro 3G/UMTS/W-CDMA) and 2400-2500 MHz (2.4GHz ISM) frequencies.

Featuring a custom designed high performance GPS patch element, a quad-band Cell, a 3G and a 2.4GHz band antenna in an ultra-thin design. The WS3947's compact and efficient design combines the power of GPS, Quad Cell, 3G and Broadband Wireless technologies within one antenna, thereby maximizing your installation options. The WS3947 is the perfect solution for cutting-edge TELEMATICS platforms.
