GPS Marine Antenna with Low Noise Amplifier

SA-200 is designed for the Marine Vessels mast or tall buildings that require long extra cables (up to 50 meters) without signal constraint to the GPS receivers.

Overview

SA-200 is the integration of the high performance GPS patch antenna and a state-of-the-art low noise amplifier into an extremely compact/fully waterproof enclosure and when connected to a GPS receiver with +5VDC antenna power it can provide excellent antenna signal amplification and out-band filtering with rejection for that receiver.
