Dunno....You never know what will happen. Will
usually vary per freq...One freq might do nothing,
and another trash everything you have...Myself,
I have a 40 dipole in the attic , fed with 300 ohm
line to a tuner, but I use it so rarely, I didn't bother
with any of that...It's just a backup, and bad wx
antenna...Myself, I probably put up the antenna, and
try it. If it trashes something, I'd concentrate on those
wires first. You never know...You might get lucky and
not need much. But...if you gotta lot of beads around,
and want to try preventive beading , while you install
the antenna, I could you could. Wouldn't hurt anything..
