Well it is like this, you want cheap or the best???
I have tried cheap and you get what you paid for like having it up
during a contest or a once in a life time dxpedition and the mast folds
over and you look to the sky gods for help and receive none.
The best is as follows:
ALUM EX 6061 T6511 QQA 200/8 TY 1
That is 2.000 OD X .500 WALL(1.000 ID)
I put up 24 feet and it cost me back in 1993 $224.0 with shipping which
was local here. I am in St. Louis, Missouri
You can only get your small finger in the wall depending how big you
are.
It weights 2.771 per foot.
You can not beat the stuff doesn't sway , no rust -- alum, and is the
best out there
Now you can be cheap and you wil pay years and years
good luck
You should have someone local there but i bought mine from
Kilsby-Roberts local supplier here in the St. Louis area
if you ned addres or phone let me know
The big-guns use it here and there are no problems
73s and take care
