There is provided a splitter circuit means for use with a CATV network comprising a signal input (34) in communication with a transformer or balun (32) to supply two signal outputs (36, 38), with a resistor (52) connected in parallel between the outputs (36, 38) and wherein additional capacitive, inductive and resistive elements (48, 50, 52, 54) are associated with the resistor (42), thereby to give an insertion loss in to out in the range of 3 to 10 dB and isolation 10 out to out of <17 dB for signal frequencies in the range 1125 MHz to 1700 MHz, while at the same time maintaining good RF performance in the frequency range 5 MHz to 1000 MHz.
