Antenna: 100 mile directional (I think it is a Channel Master 100). 10 plus years old.
Have a distribution booster, but no pre-amp. Signal splits to four TVs.
Here are my scan results:

So this setup worked great on the roof for 10 years. Moved it to a tower (slightly taller) a year or two ago and still worked great. I was getting ABC, NBC, CBS, PBS and Fox out of Columbus, Ohio.
The signal for CBS and Fox started to get intermittent and now I have only NBC and CBS. I re-aimed the antenna last weekend and all the channels came in again, but Fox and CBS were spotty. A couple of days later I am back to just two channels.
I also took out a grounding block I had before the cable went into the house. I ran the cable directly to a TV and the channels came in. So I thought that block was the problem, but now I have no idea.
Does anyone have any suggestion? I keep wondering if the connection to the antenna is weak. I can see the wing nuts are rusty, but as they are out on the end, I can't re-do them without taking the antenna down.
Would I be better off with a multi-directional?
Is 51 causing issues with 6 and can I block one to get the other?
Do I need an FM choke or something?
Thanks in advance for any ideas!
