Detail Information

Description :

The application shall apply for antenna unit which shall be used for marine AIS systems & radio car AVL and fleet management systems. The combination of high gain GPS antenna and a low profile covert VHF antenna is highly ideal for these applications that require durability, small in size, covert installation and rugged construction.
