WISCO International (CELWAVE TB-460 Series)

These RFS combiners are designed to maximize use of tower space and reduce costs by coupling multiple close spaced transmitters into one antenna. They are highly compact, modular and accommodate close channel spacing with very high isolation. The TBC and TCC are capable of coupling two or four transmitters of up to 125 Watts power rating and are equipped with 60 and 150 Watt loads respectively. Both use CC Series isolators to provide 50 dB minimum isolation.

The TBD and TCD Series use our 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

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.
