Jeff, Chuck, Larry and John
Thanks for the responses. I new about DB making the U/V version but not about
the U/U or V/V version. I think I'll opt. for converting mine to U/U and
sacrifice a little gain, but maybe improve some of the lcoal coverage with
better tilt down characteristics from my site.
Jeff - additional filtering is not a problem here. I have a bunch of Mot.
T1500 series cans available for that and several UHF isolators also.
Chuck re: my last message to you and the pigtails - the intent of the question
was to keep the lower harness still viable for returning to the original
configuration if I needed to. Cutting a TEE off doesn't let me return it to
its original operation.
Again thanks for the imput and all other comment you may have.

Better idea. This used to be order-able as a DB420D, which was really two
DB408's on the same mast, one stacked above the other, with the feeders for
both antennas terminating at the bottom. The isolation between antennas was
something like 30 dB, so again, you'll still need adequate filtering
downstairs.
