[TowerTalk] Stub mast strengthening

[Grant Saviers]

Sleeving works, UST sells 20' x 2" x 1/8 wall steel masts with the lower 
10' sleeved to 1/4".  With a 2.5" od (what is "thick wall" and what is 
the alloy and temper?) you potentially have a very strong mast.   What 
is the load?  Try one of the mast calculators before sleeving.  (ARRL,
