The first steps to a solution might be to try to minimise the
potential differences between the radio interfaces, the nearby
structure, and the operator. I would be trying to bring the feed line
down the ladder, along the chassis, and up the framework to the radio,
and to bond it to the conducting structure at 1, 2, or 3 points along
the way to try to ensure that the radio and operator are at similar
potential to the adjacent conducting structure.


Actually, that is step one, which is on the project table.
Currently, when operating HF fixed portable, I run the coax out the
coach, on the ground, and back up to the feed point. My plan is to
route it neatly from the radio location, down to the chassis, along the
chassis, out to the ladder and to the feedpoint. I suppose that, alone,
could help in my RF issues. They are not serious issues, but are
annoying at times.

Perhaps I'll reserve my ferrite split beads for a choke filter on my
fixed station antenna when I get to that.
