Distribution of HF signals to two receivers - has TV signals transmitted to input coil coupled to differential coils connected to receivers

摘要

A distributing unit receives high frequency television signal inputs and transmits to two consumer receivers. Input signals are transmitted to an input terminal (1) connected to a receiver coil (S) with ferrite core (K). A pick-off point (2) is coupled to the mid point of a differential coil (D) with a second ferrite core (K'). Output stages (5, 6) are connected to either end of the differential coil is effectively zero with respect to the transmitted current from the input coil. The upper member of the coil former has an 'E'-shaped section with the end connector forming a parallel sided slot with the long arm of the 'E'.
