WS4055/WS4065

The WS4055/WS4065 Low Current OEM GPS Antenna series with built-in connector is ideal for personal GPS applications including handheld computers and PDAs. With an industry leading 2mA current, and compact size, the WS4055/WS4065 series is perfectly suited for OEM applications. Performance is not sacrificed; the WS4055/WS4065 series features a custom designed ceramic patch element along with a low noise amplifier and SAW filter, enabling these antennas to provide a consistent, clear signal while minimizing loss-of-lock. Both models come equipped with a MCX connector. The WS4055 comes in a very compact 25 mm square package and the WS4065 comes with a 45.2 mm dia. mini-ground plane.
Designed for low power use while maintaining GPS performance, the low current connectorised WS4055/65 antenna's advanced circuitry integrates a SAW filter and low-noise amplifier to ensure a reliable and clear signal for the GPS receiver even in difficult conditions. The antenna design and industry leading low current draw makes the WS4055/65 series is ideal for portable or telematics applications using MONITOR, STANDBY or SLEEP modes.
