Using Multiple Transmitters with a Single Antenna
1. Attach an antenna to the MAIN OUT connector of the combiner.
2. Use the supplied BNC-BNC cables to connect the antenna
ports of the IEM transmitters to the RF INPUTS of the antenna
combiner.
3. Use the power cables to route power from the combiner
POWER OUTPUTS to the DC inputs on each compatible IEM
transmitter, if applicable.
Note: Use external power supplies or an optional power
distribution cable to supply power to additional transmitters. The
PA821B and PA821BX combiners do not supply DC power.
