[TowerTalk] plumb vs. level

[Mike Gilmer - N2MG]

You want your tower straight and plumb.  Small amounts 
of "off-level" in a given section are not important.  

See the tower guide I referenced earlier 

http://isddc.dot.gov/OLPFiles/USCG/010480.pdf

Nowhere do they use the word "level" to describe the 
tower or its components - but they use "plumb" in 
several spots.
