PURPOSE: A combiner is provided to reduce the size of the combiner and achieve improved efficiency of energy by using only a strip line for constituting the combiner. CONSTITUTION: A combiner comprises a housing(100) on which input pins(102,104) and an output pin(106) are fixed, wherein the housing has a path(108); a housing cover having a lower portion where a plurality of contact bars constituted by only a strip line are arranged and an upper portion where a rocker for moving the contact bars is arranged; and a main plate having an electromagnet for turning on/off the contact bars by operating the rocker when a control signal is applied from an external source. The contact bars are disposed in the path of the housing in such a manner that the contact bars contact the input pins and the output pin and select one of the transmission lines of 50 ohms and 70.7 ohms.
