I have a DB224 side mounted to the leg of a triangle tower with all the elements in line pointed directly away from the tower. It is very close spaced using some DB products clamps designed for clamping to the leg and the mast. Performance is good in all directions except where direct view of the antenna is blocked by the tower. Note this is a big broadcast tower, legs are 4" in diameter with about a ten foot tower face.

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. 73, --Don-- W8DPK
