GPS Antenna MA-700B

Specifications

MA700 is designed for the Marine Vessels mast or tall buildings that require long extra cables

without signal constraint to the GPS receivers. MA700 is not only hidden in a durable and

waterproof cover, but also cable is protected by a base which can prevent damage. The special

design for MA700 is really delicate, compact and reliable. Besides that have concinnity and

compacted design for base. 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.
