GPS antenna 80mm(Dia) x 72mm (H)
モデル : GA-88P

GPS Marine Antenna with DC 2.5~5.5V Input Voltage

GA-88P is designed for the 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.
