JTS UC-900 Instruction Manual

THE UC-900 ACTIVE ANTENNA COMBINER

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.

• Use 1/2 wave antenna or UDA-49P directional antenna to connect to the UC-900 Antenna Output. To avoid losing of transmitting
output power, if possible, please use shortest BNC –BNC cable when connect UDA-49P directional antenna to the UC-900
Antenna Output.

• Use the supplied BNC-BNC cables to connect the antenna outputs of each transmitter to the antenna inputs of the antenna combiner.

• If needed, connect the DC OUTPUT of combiner to the DC INPUT of each transmitter.

• Turn on the power and setup the frequencies of all transmitters. (All transmitters must be in the same frequency range.)

• Please turn off the power when not use or before disconnecting the cables or antenna.
