no, I did not try that to prove or disprove it. The antenna was
replaced by a diamond X-50 for a linking repeater at low height from
the ground on a hill top (20 ft)

think that dipoles get tilted, but did you try demounting the
antenna and turning it over and remounting it?

was made for 450-470 and the SWR was good at 441 (repeater output),
however, I believe there was possibly a ton of uptilt as the coverage
off
the hill was horrible (even a diamond worked better ... I know ...
don't
mention that word :) ). I would test it and see how it
does.

It is a folded dipole. I just checked Andrew's web site it is like
the
DB-411.
I didn't know folded dipoles were so broad at these frequencies. I
guess
the next thing to do is test it out
with and SWR meter.

Maybe the 406 is an older model, my catalog doesn't show it. What
type
antenna is it? If it's a folded dipole array, you should be able to use
it
as is.

Regarding a DB-406 cut for 450-470MHz:
How effective is it if used in the 440-450MHz region unmodified?
If performace is sub-optimal, can the elements be extended, and will
the
phasing harness need to be lengthened?
If it can be modified without being a labor of love, what's
involved?
(In
your opinion whould it be a waste of time?)
