GA-88P
Marine GPS antenna with Low Noise Amplifier 80mm(Dia) x 72mm (H), wide temperature
Description
Overview
GA-88P Marine GPS Antenna
GA-88P is designed for a Marine Vessels mast or tall buildings that require long extra cables without signal constraint to the GPS receivers. It is the integration of the high performance GPS patch antenna and a low noise amplifier into an extremely fully waterproof enclosure and when connected to a GPS receiver with 2.5~5.5VDC antenna power, it can provide excellent antenna signal amplification and out-band filtering with rejection for that receiver at 3V DC or 5V DC input Voltage.
