I've used insulated wire for all my dipoles over the years. Since it is
insulated, I simply tie the ends in a knotted loop and tie the rope through the
loop. Over 40 years no issues.

Thank you all for the suggestions and advice. I never thought it would
generate so many and such wide ranging responses.
I'll probably go with insulators on the ends of the wire dipole, but
probably don't need the fins and larger size of the Budwig. I'm thinking
of just a narrow, thin piece of plexiglass or Lexan, with holes drilled
in the ends, or a piece of plastic rod, like are often used to adjust
Venetian blinds. Or, I thought of just 6-12 inches of thicker, 100 lb.
test monofilament nylon fishing line, tied to a thimble in the wire and
the other end to the rope. Even when wet, I don't think that would have
much conductance.
Thanks, again, for all your help.

Cut pieces of plastic clothes hangers and drill holes in the ends for
cheap, lightweight, hard to see, insulators. That's what I use for
homemade open wire feedline spacers.
