WISCO International (CELWAVE TB-800 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. The THC and THD high power units are available in either two or four channel configuration for 350 Watt transmitters. They provide 50 dB and 80 dB minimum isolation respectively.
