WS3977 Through-hole Mount GPS Antenna

The WS3977 through-hole mount GPS Antenna provides very high out-of-band rejection performance. It 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 a compact all plastic, low profile package. Designed for permanent mount installations, the WS3977 through-hole GPS Antenna is the optimum choice for dependable, clear and consistent GPS signal reception.

Designed for maximum GPS performance, the WS3977 antenna's advanced circuitry integrates a SAW filter and low-noise amplifier to ensure a most reliable and clear signal for the GPS receiver even in most difficult conditions. Where other GPS antennas fail, the WS3977's great out-of-band rejection and low noise characteristics can provide a very reliable signal - critical for improving acquisition times and minimizing outages.

Applications
