WISCO International (CELWAVE TB-150 Series)

RFS hybrid-ferrite transmitter combiners are designed to couple multiple close spaced transmitters into one antenna. They are expandable, highly compact and accommodate close channel spacing with very high isolation.

The TBC is capable of coupling transmitters of up to 125 Watts power rating and is equipped with 60 Watt loads. It uses CC Series isolators to provide 50 dB minimum isolation.

The TCD Series uses CD Series dual isolators to provide 80 dB minimum isolation when the output hybrid is properly tuned to the antenna. A pair of two channel models may be field expanded to four channels by means of a PBH or PCH hybrid coupler panel and CAB-1 cable assembly.

Features/Benefits

� Allows combining of multiple close spaced transmitters
Maximizes use of tower space, reduces costs.

� No minimum channel separation
Can be used to combine two transmitters on same frequency.

� High isolation
Minimizes the possibility of intermodulation.

� Modular
Simplifies on-site expansion.
