Installation
Select a location for the DU 1500T that allows the connectors to be free of any possible
Contact during operation.
WARNING: Some balanced or end-fed antennas will produce high RF
voltages at the wing nut connector. RF burns may occur if touched
during transmission
1. Connect a coax cable from your transmitter or receiver to the RF INPUT connector on
the rear panel.Keep the cable as short as possible. If you use a linear amplifier,connect
your transmitter to the linear amplifier output to the DU 1500T.
2. Connect coax cable(s) from your antenna to COAX 1 or COAX 2 connectors on the rear
panel.Thes connectors are either direct from the transmitter or trough the tuned circuit
depending ont he setting of the OUTPUT SELECTOR switch ont he front panel.
3
If you are using a balanced feed antenna,connect the INSTALL JUMPER in the COAX 1
connector and switch band switch TUNED COAX 1.
4. If using a single wire antenna, connect it to COAX 1 without installing the jumper.
5. Connect a dummy load to the BYPASS connector using a coax cable. This
lets you select the dummy load from the OUTPUT SELECTOR switch. Any antenna
that does not require the use o fan antenna tuner may be connected to the BYPASS
connector, if desired.
Before Operation
1. To avoid possible damage to the DU 1500T, set INPUT, OUTPUT, BAND SWITCH
and POWER RANGE switches as outlined in the next section before applying
transmitter power. (Tuning Section)
2. Begin tuning with your transmitter with a low power setting (30 to 50W)
WARNING: Do not operate the DU1500T with the cover removed!
