Instruction Manual
The UC-900 UHF antenna combiner actively combine antenna outputs from wireless transmitter such as SIEM-111T or
TG-10STX onto a single transmitting antenna,improving RF performance by reducing signal interference and saving further
antenna system investments. A wide-band operation frequency range from 470MHz - 970MHz. Equipped with 4 DC power
outlets that can be used for transmitters, without adding external power supplies.
