Thanks, that's better.
With signals that strong, you shouldn't need the amps. WJAR has a Noise Margin of 67.4 dB. When you add the 14.5 dB gain of the HD9085P, that brings you up to 81.9 dB even before adding the gain of the amp. I suspect tuner overload; try it without the amps.

one of the tv's is connected to a HTPC with a happauge 2250 which has crappy sensitivity compared to the tv tuner
|
I have had a difficult time with the Hauppauge 850 and 950 USB tuner software. Have you added the signal monitor? It will give you useful information about signal quality (SNR and errors) which is more important than signal strength.

it works better than the Channel Master DB8
|
It should work about the same. CM doesn't make the DB8.

now I can pull in both boston stations and my locals. the sweet spot would be east but there are trees in my neighbors backyard blocking the line of sight, if I point east I get all my locals with no pixelation but then I lose the boston feed.
|
The sweet spot for Boston and the locals should be more like NE. Trees really mess with UHF signals; avoid them.

What I would like to do is get an antenna that I will be able to point north and still have enough gain to get my locals.
|
What channels are in that direction? I would think a Winegard HD7694P would be able to get your locals and Boston down to WHDH NBC if aimed about 55 degrees magnetic, IF THERE ARE NO TREES IN THE WAY.

after some research I narrowed it down to these two:

They are not suitable for you. The 7084 is a big antenna that covers VHF-Low (real channels 2-6), which you don't have. The 7698 is a big high gain antenna for distant stations, like the weakest Boston channels.

*note: the spotty signal during the day and wind hardly happens on the sony tv directly connected to antenna only with the crappy happauge.*

Maybe the Sony can handle overload and multipath from the signals filtering through the trees better than the Hauppauge tuner. My Sony TVs have a Diagnostics Screen that gives signal strength, SNR, and errors; very useful for antenna work. My latest Sony is a KDL32R400A that has a wide range signal strength scale with one dB steps. It will measure digital QAM cable signals and digital 8VSB OTA signals. See Attachments No 3 and 4.
