Really ? I have a KT-34XA, a KT-36XA and a KT-34A. All elements are insulated 
from the boom.

You can get surprising interactions. For example, I have a 2 element wire beam 
on 80 meters, supported from, and electrically insulated from a 34' boom, 
attached to the tower. That 34' boom could look a lot like a 20 meter reflector 
to the KT-36XA that is also on the tower.
