If Tom (GroundUrMast) is around, he's best to answer your query as he's in your area.
Eliminate the "AmazonBasics" (a private label Mohu Sky) and the CM 42228. The 7694 is a good potential choice, but it's hugely a PITA to fold back up if you have to take it out of the attic. The HBU33 is of similar performance to the 7694 but is getting harder to find in the aftermath of Radio Shack's bankruptcy and Antennacraft's apparent demise.
Attics are pretty much unpredictable locations for antennas. You'll never know what's going to work until you get an antenna up there and try it out.
