Wi-Sys WS4051 / WS4061

The WS4051/WS4061 low noise OEM GPS Antenna series with built-in connector is unparalleled in quality and performance, and ideal for embedded OEM applications.


The WS4051/WS4061 series features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects, as well as a Low Noise Amplifier and a SAW filter that enable these antennas to provide a consistent, clear signal while minimizing loss-of-lock when GPS conditions are less than ideal. Both models come equipped with a MCX connector. The WS4051 comes in a very compact 25 mm square package and the WS4061 comes with a 45.2 mm dia. mini-ground plane.

Designed for maximum GPS performance, the connectorised WS4051/61 antennas 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. Where other GPS antennas fail, the WS4051/61 antennas superior out-of-band rejection and low noise characteristics can provide a reliable signal, which can be critical for improving acquisition times and minimizing outages.
