Vec645 Hot Direct

The VEC-645 is often compared to the MFJ-948 or similar 300W manual tuners. While many similar tuners operate fine, the VEC-645 is lauded for its compact size, making it ideal for cramped mobile stations. Compact size ( inches), accurate metered output, easy to operate.

An antenna tuner does not actually change the physical length or resonance of your antenna. Instead, it acts as an impedance transformer between the radio's 50-ohm output and the complex impedance of the antenna feedline. When matching extreme complex impedances (such as a short mobile whip on 80 meters), high circulating currents flow through the internal inductors and variable capacitors.
