Jim-
When I read your message, the first thing that popped into mind was a flag
pole.
Raised the flag most of the time, raise the 6 pound antenna other times.
In a more direct answer, with just a 6 pound load a length of fencing top rail
might
serve you very well - just go visit a local fence company and see what diameter
(and
weight) might serve you best. If you have room, a simple pivot at the base and
a
eyebolt at the lifting point might be just the trick for you.
