I used two 20' lengths of 3" for my 4 el 20M yagi around 1984. Used about
18" of Schedule 40 AL pipe as a strong splice and for the boom to mast
plate. Took it down in 89 and put back up here in 91 where it remained as
part of the 4/4/4/4 on 20M on a rotating side arm.
That boom and elements survived everything this hilltop could throw at it
when I dismantled the contest aluminum farm of up to 19 HF yagis on 4 towers
about 10 years ago. It is all resting on several sawhorses out in the back
woods.
