There are questions that need to be answered!
Are you using the tower for a reflector?
The rule of thumb is to be at least 1 wave
length off the face of the tower at the transmit
frequency some times more. We need to know what
you want for a pattern? Omni get your DB-455
away from the tower. Placement on the face as
well will makes a differents. We need more
input as to what you want to do. Just hanging an
antenna on a tower is not enough. Plus there is
always tower loading. IE antenna, feed line,
grounds,
clamp, bracket and so on. I can reply to one of
your questions. That being YES you will need a
top bracket on a 455. If you would like you can
call my office and we can chat on what you are
trying to do. (877-992-2665)
