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.
