rf antenna cable

rf antenna cable (SiRF Star III)

The MR-350 GPS Receiver can be utilized in a variety of applications that require a permanent mounting configuration. With bulkhead (through-hole) mounting and a low-profile housing, the MR-350 is completely self-contained and waterproof. It incorporating the latest SiRF Star III GPS chipset and an active patch antenna so you receive a high degree of GPS accuracy.

Typical application can include marine environments, aviation, commercial use such as fire truck, police cars and utility vehicles and buses. The extended 4.5 meters cable allows for easy routing to your PC behind headliners and side panels and terminates to a custom PS/2 connector for interfacing with one of the available cable kits that is purchased separately (USB/RS232).
