Thats not the problem. Most of the time I operating in
Red Cross Shelters and the Radio and antenna are going to be in close
proximity. Last year, I was at a shelter during a hurricane and the
antenna had to be indoors. In theses situations, I need High power to
get throught the walls of the shelters.


Any Ideas.


There's more than one way to reduce the level of stray RF inside the
case.

If you're using an omnidirectional vertical, you'll have a null on the
radiating element's axis. If you can elevate the antenna that should
help. If you can achieve some measure of horizontal separation as well,
that will also help. The ferrite beads won't be wasted either, as they
will add a lot of loss to the RF flowing down the power line and the
microphone cable without affecting the DC current or the audio tones.

And if push comes to shove, there's always the steel toolbox to fall
back on.
