The WS3915-HR Very Low Power No Interference GPS Antenna has the industrys lowest power consumption and best out-of-band filter performance.


The WS3915-HR features ESD circuit protection, a patented very low power two-stage low noise amplifier and a dual SAW high rejection filter. It also features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects. The WS3915-HR provides the most consistent, clear GPS signal reception while minimizing loss-of-lock in high-RF fields. Housed in a weatherproof magnetic or screw mount enclosure, the WS3915-HR is ideal for most demanding, power critical GPS applications.
