Abstract: PROBLEM TO BE SOLVED: To eliminate insertion loss due to physical connection of transmission lines from many base stations at a common connection point by preventing interference by sufficiently separating frequency bandwidths allocated to different radio system. SOLUTION: In the system and method for effectively connecting communications of base stations of many radio system, in an embodiment, a radio system combiner servers as an interface between base stations of 1st and 2nd radio systems ('1st base station' and '2nd base station') and a common antenna to greatly remove spurious noise from the 1st base station at the frequency allocated to the 2nd base station to prevent the transmitting electric power from the 1st base station from being sent to a receiving circuit of the 2nd base station in the common antenna constitution. The combiner includes a 1st combiner filter between a duplexer of the 1st base station and a common connection point and a 2nd combiner filter between a duplexer of the 2nd base station and the common connection point.
