REQUEST PRICING

These antennas feature a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects, ESD circuit protection, a patented two-stage low noise amplifier and a dual SAW high rejection filter. The WS3951-HR / WS3961-HR antennas provide the most consistent, clear GPS signal reception while minimizing loss-of-lock in high-RF fields. The WS3951 comes in a compact square package and the WS3961 comes with a 45.2mm diameter mini ground-plane.
