Mechanica properties:
Cable Temperature Rating: 75 centigrade

Electrical Properties:
Impedance: 50Ω

Application:
Used as connection cable in the high signal sequences of the wireless and data communication systems where lower attenuation required.
50 ohms coaxial cables are used in most radio Frequency and Microwave transmission, local Area Network (LAN), computer and many instrumentation /control applications.
It is used here because it matches nicely to many common transmitter antenna types, can quite easily handle high transmitter power and is traditionally used in this type of applications
