FEATURES
The DU 1500T optimizes the performance of your antenna and transmitter or SWL receiver by providing adjustable impedance matching. The DU1500T also measures the Power and Standing Wave Ratio (SWR), which allows you to tune the indicted SWR to the lowest possible ratio for the selected transmit frequency.

FRONT PANEL FUNCTIONS
Continuously adjustable output capacitor.
Five-position rotary switch an output coaxial connector.
1.TUNED COAX 1 selects the COAX 1connector trough the impedace matching circuit.
2.TUNED COAX 2 selects the COAX 2
connector trough the impedance matching circuit.
3.DIRECT BYPASS selects BYPASS COAX connector bypassing the impedance matching circuit but provindingSWR, FORWARD, and REFLECTED power meter readings.
4.DIRECT COAX 1 select the COAX 1 connector bypassing the impedance matching circuit but providing SWR, FORWARD, and REFLECTED meter readings.
5.DIRECT COAX 2 selects the COAX 2 connector bypassing the impedance matching circuit but providing SWR, FORWARD, and REFLECTED meter readings.
5.RANGE SWITCH
Two-position switch selects the range
(200W or 2kW) of FORWARD and
REFLECTED Power displayed on the power meter.
When the METER (power range) switch 200W the FORWARD meter
Scale reads 200W full scale and the REFLECTED meter scale reads 40W full scale.
When the METER switch is on 2kW, the FORWARD meter scale reads 2kW full scale and the REFLECTED meters scale reads 400W full scale.
