A lot of people with questions on this topic.. might as well join <G>.
I AM FORCED TO buy my tubing locally as I want a one piece 20 footer
with about 4' in the tower. no biggie, got pipe yards all over this
town. two or three within 5 miles. just need to know how HEAVY the
tubing needs to be.
20' gives me plenty to stick out of the top of that 52' crank up, tilt
over to support a UHF/VHF stick, a screwdriver on the very top
and on the other side of the yard arm from the Diamond 50, a set of
pullies for supporting a couple or so dipoles. I would like to have
at least 15' out the top.
I expect that I may point a set of 2m, 11 element yagis at Austin/SAT
and another towards Lufkin. from my QTH vic Jersey Village or NW
Houston - 150 miles to hit the repeaters in those towns. Might need
to goose the TX with some amp <G>.
Any suggestions for tube dimension to support that amount of antenna?
I will crank it down for the next IKE before it comes thru.
TIA
