John,
If you want to place a balun at the transposition point from coax to the stub, try it and have fun.
The voltage and current curves will not change as the physical length of the stub will not be changed. Whatever feedline radiation is present will just add to the hash that has to be eliminated.
A good solution would be remove the coax and feed the antenna with open wire line to the shack.
It could even be matched properly by using a link coupled tuner, either a Johnson matchbox or homebrew unit.
Using this method the antenna and feedline would be balanced in regard to ground, minimizing feedline radiation. Our goal is to keep the radiation away from the receivers as much as possible.
Feedline to feed the antenna and the radiator to radiate, pretty simple concept.
Other antennas would work, but I've been told by management not to broach the subject of a proper antenna farm.
