[TowerTalk] Using aluminum tubing for masts

[David Thompson]

Atlanta based JM Tull (now Ryerson) sold thick walled 20 foot pieces of 
aluminum tubing for use
as masts.  I saw the specs and they matched the heavy strength steel masts 
and weigh less than 1/2
so they are easier to mount.  The price was higher
so you had a trade off.

The typical installation in the Atlanta area was 5 element Hy-Gain Long 
Johns for 10, 15, and 20.
