Thanks for the ideas.
The question was prompted because I don't want to take the antenna down for
a check or repair, and I don't know how well my readily available materials
hold up under UV and heat.

How useful is it to have plastic tip caps on an antenna you cannot reach?

If the antenna is made of hollow aluminum tubing it keeps rain, snow and
insects out of the tube.


I could understand that you would want a spherical tip end to reduce
the risk of arcing, but it would need to be metallic and would not suffer
from UV or heat.
