935-6 Series Constant Impedance FM Combiner Module
The ERI Model 783 Series Constant Impedance FM Combiner Modules provide stable high performance combining system for high power multi-station FM combining systems.
Description
The ERI Model 935-6 is a low power constant impedance configuration utilizing two 935 Series, three section FM band pass filters with input and output 3 dB hybrids. The filters and hybrids use a high quality aluminum construction. The filter is floor mounted or can be suspended from the ceiling. The 935 Series is also available as a reflective filter. The 935-6 Series maintains a compact profile while maintaining high performance. The temperature compensated design is perfect for any low power FM Analog or IBOC application.
