How about a ClearStream 5 for VHF-hi duty? AD claims a 70* beam width. Kinda pricey, but if it works, it works.
Solo? Or maybe teamed with the CS2 for UHF? Or DB8e?

The CS5 is well made, doesn't have quite as much gain as the 7694, and comes with a UHF/VHF combiner, BUT
Umm, you are getting a little ahead of yourself. You are at the point where you need to put
something in your attic, to see how well it works, and go from there.
In order to evaluate the result of changes, you need to be able to measure signal strength and signal quality (SNR and errors).
What make and model is your 60 inch plasma TV? Does it have a signal strength indicator?

I just took delivery of a new Tivo Roamio OTA
|
The Roamio should have a Diagnostics Screen that looks like this:
I think it's here, IIRC:
From TiVo Central > Settings & Messages > Account & System Info > DVR Diagnostics
ADTech and I spent a lot of time (8 pages!) helping mulliganman with his Tivo Roamio. I thought his problem was multipath. Then I thought it was signals too strong. Then I thought it was multipath again because his C2V was in a poor location, which was correct. His TV and his CM DVR did a little better than his Roamio with the poor antenna location. I had him make some tests using the Diagnostics Screen to check signal strength, SNR, and Errors. He finally moved his antenna to a better location.

Then I had him insert attenuators of different values to see what would happen to the signal strength, SNR, and Errors to see how much signal strength was required for good reception, and to find out how much signal margin to dropout was available to deal with changes in OTA signals
