DC Solar Cables

WALNA Coaxial Cables are used as a transmission line for Radio frequency Signals. It's applications include feed lines connecting radio transmitters and receivers to their antennas, computer network (Internet) connections, digital audio (S/PDIF), and distributing cable television signals. One advantage of coaxial over other types of radio transmission line is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors. This allows coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other types of transmission lines. Coaxial cable also provides protection of the signal from external electromagnetic interference.

Application

Common applications of coaxial cable include Video and CATV distribution. RF and Microwave Transmission, computer and Instrumentation data Connections.
