[Repeater-Builder] Side-mounted DB-224 performance

[Don Kovalchik - W8DPK]

Our club has permission to mount our brand-new DB-224E on the side of 
the local hospital's tower, about halfway up (90').  We want maximum 
signal to the north-east, so will be mounting the antenna on the NE leg 
of the tower, with all 4 elements on the NE side of the mast.
Is it necessary to use a stand-off bracket? Or would it be OK to mount 
the mast right next to the tower leg using the bracket(s) that came with 
the antenna?  I don't care about performance to the south-west; actually 
a null to the SW would be good to minimize interference from a 
co-channel system only 100 miles away.
