3.5 Connecting to transmitter
There are six functionally identical HF signal output
interfaces on the transmitter. Each one can connect up
to 30 radiators by daisy chain. The radiators are
connected with RG-59 cables. The maximum cable
length per output is 300 m. Automatic cable termination
is achieved by a built-in switch in the BNC connectors
on the radiator.

3.6 Output power selection
The radiator can be switched to half power output. This
is usually done when full power output is not needed,
e.g. when a portable system is used in a small venue.
Switch a radiator to half power if an adequate airflow
cannot be guaranteed, e.g. if the radiator is mounted
on the top of an interpreter booth. Reduce the power as
often as possible to save energy and to increase the
lifetime of the radiator.
Note:
For the automatic cable termination function,
do not leave an open-ended cable connected
to the last radiator in a loop-through chain.
