The insulator loop will work. Anything that amounts to a strain relief will
work.
What I do in a very similar situation is tie some nylon cord (in a series of
about 10 tight half hitches) around my insulated vert wire, than tie the cord
to the feed point balun box mounted on the supporting tree. The cord grips the
wire's covering. I make the cord short enough so that all the stress is on the
cord, and the wire simply makes a small half loop below the wrapped cord to the
feed.
I trim the resonant frequency by shortening or lengthening the vert wire via
one or more fold-backs of excess in the wire taped tightly to the main vertical
run. I'm using seven tuned elevated radials on a small lot, and the resonant
freq shifts as the ground and trees freeze and thaw in Alaska.
