Abstract

The junction or tap to a co-axial or twin wire transmission line has input and output impedances equal to that of line when terminated in its own characteristic impedance. The several forms of tapping are either 'T' or 'TT' networks involving the use of either ferrite cylinders or wound coils slipped over the line or lines and transformers or resistive coupling to form the four terminal network. A further form applicable to bifilar systems uses a single ferrite block through which both lines are threaded together. A conductor forming several turns within the block provides the tapping connection.
