DU1500T Diff. ANTENNA TUNER 

FEATURES 

The DU1500T Diff. optimizes the performance of your antenna and transmitter or SWL receiver,by providing adjustable impedance matching.

The DU1500T Diff. 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.
