[TowerTalk] Rotor location

[K7LXC at aol.com]

>  I now have my Rohn 25 tower assembled awaiting my concrete  to cure 
before erecting.
I am getting ready to mount my rotor. At the top of  the Rohn 25 sections I 
am using A BPL25G thrust bearing assembly section which  has the top plate 
approximately 18" above the 1st section of cross members. My  plan is to 
place the rotor at the 2nd set of cross members on the top  section.
Is this a good distance from the thrust bearing? If not, how much  spacing 
do I need and why?
 
    There are only 2 places where the rotator shelf  will fit - either at 
the junction of 2 sections or in a top section that has the  diagonals 
missing; e.g. BPL25G. Your choice.
 
Cheers,
