Connecting to
Transmitter
There are 4 functionally identical HF signal output
interfaces on the transmitter. Each one can connect
up to 30 Aladdin RAD25 radiators in daisy chain. The
radiators are connected with RG-58 cables. The
maximum cable length per output is 900m.
Automatic cable termination is achieved by a built-
in switch in the BNC connectors on the radiator.

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.
