End of Line

Radiating "leaky" cable systems, in which radio signals are transmitted from a cable rather than from an aerial, can provide two-way radio services in situations where conventional VHF and UHF communications from central areas are not practical. The radiating cable End of Line Terminator is used to prevent unwanted radio frequency reflections presenting themselves within the cable. These unwanted reflections cancel out the wanted signals and radically affect the "throw off the cable". The unit terminates the radio signal in the characteristic impedance of the radiating cable, but does not present any DC current load to the system.
