DIGITAL BARGRAPH ANTENNA TUNER

FEATURES

The Vectronics VC-300D Antenna Tuner optimizes the performance of your antenna and

transmitter, receiver, or transceiver by providing adjustable impedance matching. The

tuner also measures the Power and Standing Wave Ratio (SWR), allowing you to adjust

for the lowest possible ratio for the selected transmit frequency. It utilizes a precision

frequency compensated lighted dual movement SWR/Power meter which can show either

peak or average readings. Also included is a built-in dummy load for tuning purposes

which is easily switched in and out of the of the circuit. The tuner features a

revolutionary new digital bargraph display that enables you to see real peak SSB power

relative to full CW power. Levels and delay are front panel adjustable.
