Marine GPS Antenna

Inquiry PDF

Product Description

MA700C is designed for the Marine Vessels mast or tall buildings that require long extra cables without signal constraint to the GPS receivers. MA700C 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.
