FI836 Integrated High Power FM Channel Combiner

The FI836 is a compact solution for combining two FM station into a single antenna. This is a single cabinet solution that is an economical alternative to traditional modular systems. The band pass filters are integrated into a single compact floor mounted cabinet that requires little or no on site combiner assembly. The filters are temperature compensated and the standard combiner configuration includes directional couplers at the combiner inputs and combined output.
