Hello,

I have two antennas that I am trying to combine, and have a question
in regards to the best way to do this. The first antenna is a
Winegard HD7084P (FM/VHF/UHF lpda) that is hooked to a preamp and
tuned in perfectly. I want to add my other antenna (Winegard PR-8800
UHF bowtie) that is also tuned in and points in the opposite direction
(almost 180 degrees) to pick up some UHF stations.

..........................................

Over the past 50 years several antenna manufacturers have come up with
kluged arrangements to do what you propose. None worked, except in a few
special cases where the signals were very strong. What you need is an
antenna rotator, or a second antenna with its own feedline. When you combine
the outputs of two antennas without appropriate filters, not only is there a
chance of signal cancellation, but you will also quite likely have a severe
echo problem.

I wanted the same set up as you did using a Winegard HD8200P (combo) &
HD9095P (UHF). In the end I unhooked the UHF in the HD8200 and get VHF
(from the 8200) from one direction and UHF from another direction. I
could not combine the two and receive a good UHF signal. I will say that
my HD9095P does recieve one channel 180 deg from where it is pointed.
You might want to play with the UHF reflectors (try folding them down
some maybe) to get more 180 deg. signal.
