Dan,

I'd ask "Where does stray RF flow now, and where do I want it to flow when I'm 
done?"  I imagine you really do not need RF in or on your control cables to 
begin with, and with this in mind, the question answers itself: Bypass where 
you want stray RF current to GO, and put your ferrites just past that point, to 
steer it there.

Cheers,

Cortland

If I am going to use ferrite to control the problem, should
I put the ferrites on the cables at the base of the tower,
i.e. before the 70' run along the ground to the shack, or
at the wall of the shack?

I assume that the right answer isn't ferrite, but rather
to bypass the cables to ground using caps.  Again, if I
am going to do that, should I do it at the tower end,
or the shack end?
