4 Channel Combiner
Star Point Type
FM Band 87.5-108 Mhz

The star point combiner basically consists of connecting several transmitters, in parallel to a single antenna system through suitable bandpass filters, each tuned to each individual transmitter frequency.
The parallel connection is obtained by means of coaxial lines of determined length, to provide for adequate isolation between transmitters.
