Abstract: A CATV converter of a dual frequency conversion type is constructed in a chassis divided into compartments for accommodating respective stages between the input and output terminals. The primary and secondary local oscillators are disposed apart with other compartments interposed therebetween thereby to enhance the input to output isolation.
