Thanks for the excellent photos. Your antenna is an RCA ANT751 for UHF and VHF-High channels, which is what you have.
If you want to upgrade, you might consider the Winegard HD7694P aimed at 187 degrees magnetic.
But first, you might want to raise your RCA antenna by adding a 5 ft mast to the satellite mount. I wouldn't go any higher, even though the mount has braces.
If you want to try the Winegard HD7694P, I suggest a mast coming up from the deck supported at the base and supported near the roof by a wall bracket. If the antenna doesn't have a clear path there, move it.

I noticed it lately, when I watched the local PBS channel at 9-*. The strange thing is channel 11-* for CW is not affected at all.

Not too strange with 2Edge signals and your location behind a hill. Channel 9 is running less power and its antenna is at a lower elevation.
