Default matching masts as vertical antennas.

You might try the matching system used on the old "Gotham Vertical".
This uses a tapped coil from the base of the mast to ground. The top
of the coil is tapped down until resonance is found. Coax braid is
to ground, and the coax center conductor is tapped up from the bottom
of the coil for best match.


Whilst this system might work for an antenna with a capacitive feedpoint,
will it work for an inductive feedpoint such as this ~3/8 lambda attena?

Just add enough coil to bring it to 3/4 lambda resonance. Wouldn't that
work?
