Direct Current Shorting Coupler

A coupler which is specifically designed to be inserted into a coaxial transmission line to permit the flow of radio frequency electrical energy while providing a circuit between the center and outer conductors for signals below 20 kilohertz (kilocycles). It consists of a short section of coaxial line which has a high impedance line shunted across the inner and outer conductors. See coupler (1), direct current blocking; coupler, directional; and coupler (1), transmission line.
