[TowerTalk] 12 Feet of Alcoa T651 Solid Aluminum Useful?

[n4kg@juno.com]

Most of the strength of a mast is in the outer portion.
Filling in the center does little except add weight.
You didn't mention the diameter.  Anything less 
than 2 inches should not be used for more than
a few inches above a tower top for HF antennas.
