[TowerTalk] Strongest mast material?

[Joe Subich, W8IK]

Double or even triple walled mast is a waste of time and money. 
If your mast won't handle the load, use a larger diameter 
mast.  The strength (specifically the reduction in stress) 
ingreased in proportion to the [outer diamer]^4.  An .125" 
wall 2.5" OD mast is much more capable of handling a load 
than a .5" wall 2" OD mast!
