WS3971-HR Anti-jamming Permanent Mount GPS Antenna with dual SAW High Rejection Filter
The WS3971-HR Anti-jamming Permanent Mount GPS Antenna provides 28 dBs of gain and very
high out-of-band rejection performance. It features a perfectly tuned custom ceramic patch element for
maximum signal reception, a dual stage LNA circuit and a dual SAW out-of-band filter, enabling the
WS3971-HR to provide the most reliable and clear GPS signal reception while minimizing loss-oflock,
even in high RF fields. Available in an all-plastic, non-corrosive low profile package for mobile
applications or with a dark grey or white cone-shaped radome for fixed installations, the WS3971-HR
Anti-jamming permanent mount GPS antenna is the optimum choice for critical GPS applications with
high RF fields.
