[TowerTalk] R45 top prompted by Leeson comment

[tgstewart@pepco.com]

I sincerely doubt this is a problem.  I'm no engineer, but since it is only
the last couple of feet and there is no twisting force at the very top of
the tower, there really is no reason for them.  Remember that all of your
twisting forces will be from the rotator down, assuming that your rotator
is even with or above the top set of guys.  Do you know of someone who has
had a problem?  I dont.

I like Dave's idea of using a regular Rohn 45 section as the top section
rather than a "top section."  My other tower has a regular one.  The Rohn
"top section" lacks the diagonals for the top several feet, I guess for
ease of rotator installation there...many of us with longer masts are
putting our rotator further down anyway.  So the top several feet of
tower must be weaker than the rest of the tower that has diagonals.
