A few  inches is fine.  I'd probably go 6 or 8 inches, but  even 3 or 4 
wouldn't  worry me.   You just don't want it to touch or be  so close as to 
have it couple electrically with the tower.

I doubt if you are going up the tower anytime soon, so perhaps a  slightly 
longer  standoff at the bottom would do.   Something  like 15 inches or so 
of 1 1/4 or whatever pvc  at the bottom  of the tower will pull it away real 
nice.   It won't be a thousand percent vertical, but as my old man used to 
say " You'll never see it from Broad Street."
