Where are these ground paths?

anything that has an electrical link that reaches the coax sheild
TV's, a person's hand touching the case of a reciver, anything that makes contact with the ground of a reciver (HDMI cables, other connection cables

its fully possible that the splitter is dieing but saving everything else

a code violation is a code violation and having another home's ground in your home and still thinking of them as ground is just going to lead to something bad

do it right or expect problems, and the right way is a ground block at one of the (or both) homes and bonding the ground rods

Quick update. The temp dropped to 25 degrees and I had problems with signal strength on rec 1 tuner 1 (my normal place for problems). signal strength was 75 to 88 on different transponders, where the signal strength we 96+ during warmer weather. I did notice that no one was bitting on my cold weather theory. I replaced the splitter off the PI with a directv approved MRV green lable splitter and all is right with the world again.

I was using a Holland HFS-2D 5-2150 MHz diode steered splitter. Could this have been my problem all along. The splitter and PI are in my equipment closet and enviromentally controlled. There is still some direct correlation with the outside tempature and signal strength on my recievers.

I purchased a new green labled PI and SWM8 and will install them later, but I want to let this run and see if my problem reappears.

Quick update: Just got back home the the problem is back (and worse as measured by signal strength). BTW. Temp is much colder. I'm going to replace the PI today and see if there is any improvement. Replace the SWM8 later. just trying to step through to isolate the problem.

I'm going to call my electrician to provide me a grounding wire on the roof.

Let everyone know what I discover. And thanks again for the contribution.

BTW, I'm surprised that no one (many installers and myself) didn't notice the lack of grounding earlier.
