• Rohs Compliant: YES

Designed for maximum GPS performance, the
very compact WS3997 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 WS3997’s great out-of-band rejection
and low noise characteristics can provide a
very reliable signal – critical for improving
acquisition times and minimizing outages.
