Combiners allow several radio channels to operate at one site using a common antenna. The MCPS 210 V Star Combiners are composed by 210mm cavities and a star connection combining from 2 to 8 channels in the VHF range. Their high power rating make them ideal for working with AM transmitters with high peak power. The input and output loops can be adjusted for the optimum combination of selectivity and insertion loss. The combiners can be supplied with or without external isolators.
