WS3910: Unparalleled in quality and performance

The WS3910 Very Low Noise GPS Antenna has the industryâ€s lowest noise figure. It features ESD circuit protection, a patented very low noise LNA and a high rejection SAW filter. It also features a perfectly tuned custom ceramic patch element that minimizes detuning effects caused by adjacent objects. The WS3910 provides the clearest GPS signal reception while minimizing loss-of-lock in even in less than ideal conditions. Housed in a weatherproof magnetic or screw mount enclosure, the WS3910 Very Low Noise GPS Antenna is clearly the best choice wherever top GPS performance is required.

Designed for maximum GPS performance, the WS3910 antenna's advanced circuitry integrates a SAW filter and low-noise amplifier to ensure a reliable and clear signal for the GPS receiver even in difficult conditions. Where other GPS antennas fail, the WS3910â€s superior out-of-band rejection and low noise characteristics can provide a reliable signal - which can be critical for improving acquisition times and minimizing outages
