I had a DB404 (I think that was the number, two dipoles each side of the stick, 5 or 6 ft long?). This 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. Steve WA6ZFT

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. Chuck WB2EDV ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Monday, August 09, 2004 4:02 PM Subject: [Repeater-Builder] DB-406 450-470MHz how useful on 440-450MHz?
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?)
