I have the wireless microphone half of the Panasonic Arbitrator Camera system that is used by Police Departments in their vehicles. It is new and has only been bench tested by me. Comes with the wireless mic that is worn by the officer and the base unit which installs in the cruiser. Has both the internal and external vehicle antennas. Transmits 600-700Mhz and has 100 available channels. This is an all metal unit and is extremely rugged.

Does not suit my purpose. Comes with the manual.

Would accept offers over $100 US.

Thanks
