I have a Rohn 25ag2 top section (used);  this is the tapered top section that 
has a single vertical tube at the top.  It appears that the way the rotor and 
mast were mounted was rotor on a plate inside the tower a couple feet down from 
the top,  and the mast running through the inside of the tower section's 
vertical tube.  Is this a reasonable way to do it?  Should there be a bushing 
inside the tube (there is none now)?  Won't friction be pretty high? Do I 
grease the mast?  Will it ice up badly? (I live on a very windy, cold, icy 
    My rotor has an adaptor that allows me to mount it directly to the 
section's vertical top tube,  but it is not as strong as mounting it to a plate 
inside the tower section.  This will be a temporary installation for the 
winter,  30' or 40' high.  I'll have a couple of long VHF yagis on it.
