Hello:

I have been trying to find the answer to my question on the front-to-
back ratio on UHF antennas, and so far have been unsuccessful.

I think I understand what the front-to-back ratio is, but the specs on
my Winegard PR-8800 (8 bay bowtie) show negative front-to-back ratios
(-9 dB @ ch 14; -17 dB @ ch 32; -11 dB @ ch 50; -9 dB @ ch 69). The
"dB over reference dipole" is: 10.7 dB @ ch 14; 12 dB @ ch 32; 11 dB @
ch 50; 12.5 dB @ ch 69. How can the front-to-back ratio be negative,
and is this good or bad? I am assuming this could be bad in my case
as I would like the signal at the back of the antenna to be minimal.

I am currently trying to improve our HDTV reception. I currently have
the PR-8800 antenna in our attic hooked to a Radio Shack 30 dB mast
amp. This antenna works very well overall. But from time to time, on
a couple channels the HD signal strength will drop all the way down,
enough to drop the signal or cause break-up. I've been considering a
Winegard HD9095P or PR9032 to use in conjunction with the PR-8800
since they have a higher gain than the PR-8800, then rotate the
PR-8800 the other way to receive some different stations.

I really appreciate the help and feedback on this!!

Thanks,

Get that antenna OUT of your attic. Put it outside on your roof, no
more than 12 feet mast. All your problems will go away.
