[Towertalk] Universal aluminum

[S. J. Blackwell]

I have had a Universal tower up for over 25 years. Two years ago took it 
down and moved it to a new location. The tower remains in good condition. 
The same cannot be said for the grade 8 bolts that anchored it to the base. 
Watch out for these steel bolts. Electrolysis.
