Wi-Sys WS3951

The WS3951 Embedded GPS Antenna series has the industry's lowest noise figure.


It features a perfectly tuned custom ceramic patch element that minimizes detuning effects caused by adjacent objects. As well it features ESD circuit protection, a patented LNA (low noise amplifier) and a high rejection SAW filter which enable these antennas to provide a consistent, clear signal while minimizing loss-of-lock even when GPS conditions are less than ideal. The WS3951 comes in a compact square package.
