The RM 35/600 is a 9 pole Chebyshev Low Pass Filter that is designed to be used for effective harmonic attenuation when transmitting within the 24-30 MHz band. It features low insertion loss of less than 0.15 dB and a stopband attenuation of greater than 50 dB at 50 MHz. Installation is very simple, the filter should be inserted directly at the output of the radio/amplifier and its output connected to the antenna. In the case that an antenna matching network is required the AMU should be connected on the output side of the filter. The filter is labelled RTX for the input and ANT for the output., however it is actually a bidirectional network so can
