Any,
I think one way is to feed the antenna as a top loaded vertical. What you
do is at the end of the coax (the PL259 connector) you short the center to
the braid. Then you treat it as a single wire, as if it was the bottom end
of a vertical. Use a tuner. You will need a ground on the tuner.
The most optimum arrangement would be for the tuner to be sitting on the
earth, right under the centre of the dipole with the coax coming straight
down to it, and with a series of radials out all over the ground from the
tuner. This will probably not be possible so you start making your
compromises from there.
