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 WS3961 comes with a 45.2mm diameter mini ground-plane.
