A simple way to make a center-fed half-wave dipole multi-band is by
using alligator clips to disconnect outer section a dipole in order
to run on a higher freq band.

Simple make a dipole for the lowest freq of interest and then cut the
wires at the length for the higher band, attach an alligator clip on
the end of the shorter wires and connect the end wires to the shorter
wires by use of a small nylon cord.

We made 80/40m dipoles for use on the Iditarod Sled Dog Race in this
manner and its called an: "Iditarod Special".

Most of the remote checkpoint stations use this for an antenna
running 100w HF radios to provide race communications support back to
Anchorage HQ (Often distances of several hundred miles).  Often the
temporary dipoles were hung pretty low to the ground so they operated NVIS.

Side Note: I just disconnected my old Drake MN-2000 tuner as the
auto-tuner in my KXPA100 does the job easily.  I use either KX3 or K3 with it.
