Four Station FM Channel Combiner in Final Assembly

This is a four (4) station constant impedance FM combiner system for four Full Service FM stations. The operating frequencies of the FM stations in the combiner system and collocated with the Master FM Antenna these four station will use are all closely spaced channels so the band pass filters in the system are all four-pole and include optional non-adjacent coupling loops to provide additional suppression at the band edges of each filter bank while reducing group delay variation.
