Another alternative is the 21-foot semi-rigid power pole insulators sold by
Joslyn. 5 years ago mine were $50 each. A set of these separating the
tower from the inside end of the top guy will do a lot to prevent
interaction with a 20-10m tribander. I discovered from experience, though,
that they are not long enough to prevent interaction with a 40M yagi, or
with the bottom antenna of a stack placed inside the guys.
