[TowerTalk] Tower buried section legs -- Buried in Concrete orBelow the C...

[Roger (K8RI) on TT]

Setting the base in a solid medium, means the tower has to tale all the 
torque while with the pier pin base, the guying system has to take all 
the torque.  I believe torque arms are a poor substitute for a star 
guying system

I'd certainly not climb 30' of free standing 25G to install permanent 
guys after a friend was permanently disabled when 30' of 25G broke 
over.  My 45G base is in cement.  Knowing what I know now it would be on 
a pier pin base, but any way I think the third section should have 
temporary guys on it when it goes up.  Every section should be plumbed, 
or at least leveled in the vertical plane on 2 legs.  I've seen some 
small towers, including one 25G that were not as straight as they should 
have been.  Using guy tensioning order to straighten these can put 
additional stress on sections and joints reducing the tower's overall 
strength for both weight and wind load..  It might be much, but it might 
be enough to be a problem with weight, or antenna area in high winds.

Of course, I don't know any hams who load a tower with the idea that the 
built in safety factor will make it safe.
