MA-25
GPS Marine Antenna
The MA-25 GPS Marine Antenna has RF protection circuits built-in to guard the active LNA (Low Noise Amplifier) and High Gain signals as well as being able to accept a wide-range of power supplies from 3 V ~ 6V. The MA-25 GPS Marine Antenna offers ultimate performance for Marine and Networking applications. MA-25 GPS Marine Antenna is designed for maximum ruggedness in marine environments. Please Note: This antenna is A- 132 Flange GPS Antenna with a waterproof and sun-proof housing. It is a screw mounted antenna, and is usually installed on top of a vehicle or a boat.
