The WS3977-DH through-hole mount GPS Antenna provides very high out-of-band rejection performance.


The WS3977-DH features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects. This element, along with a low noise amplifier and SAW filter, enables the WS3977 to provide a consistent, clear signal while minimizing loss-of-lock when GPS conditions are less than ideal. Housed in an all-plastic, charcoal grey or white radome cover for fixed installations, the WS3977 through-hole GPS Antenna is the optimum choice for dependable, clear and consistent GPS signal reception.
