Designed for low power use while maintaining
GPS performance, the WS3914 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.
leading low current draw makes the WS3914
antenna ideal for portable or telematics
applications using MONITOR, STANDBY or
SLEEP modes.
