DU 1500 T ANTENNA TUNER 

FEATURES 

The DU 1500 optimizes the performance of your antenna and transmitter or SWL receiver

By providing adjustable impedance matching.The DU 1500 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.
