What else can make an 85 drop to 25 strength.
Usually 1) electrical interference or 2) multipath interference.

Maybe I have too big of an antenna?
Nope.

What I've noticed is all 30 channels I get either come in great or drop out, mostly together.
That means a common element is at fault. Start with a temporary coax straight from the antenna to a single set, bypassing all coax and accessories in use. You didn't mention any amplifiers, but do be clear if any are in use or not. Check the phasing lines on the antenna to make certain they are both correctly routed (not touching boom or unintended elements) and are correctly connected.

I think maybe it's multipath.
If there's nothing out in front of the antenna, it's not multi-path. Multi-path occurs when the direct signal path is blocked.

it's now 4' above my one story roof ridge, and am going to try aiming it a little bit different. It's close to the 227 degrees recommended now.
Do you have a metal roof or radiant barrier decking or foil on the underside of the roof deck? Is the antenna situated on the signal side of the house or must the signal cross the roof to get to the antenna?

Does the antenna "look" into power lines?

I looked for some of those little caps to terminate my unused splitter terminals, but they are hard to find.
Downsize the splitter to one with the correct number of outputs. What are you currently using for a splitter?
