C5Guy-
I live very close to you in the Gold River area and PBS is always one of the strongest signals for me. When I read this posting I changed over to PBS to check it out. As I type this PBS Digital 006.1 is coming in strong and steady with a signal strength of 82 with just a $20 RS Yagi mounted in my garage feeding into a Dish 6000u. Odd that you have such trouble with it, but then again, you are in the hills.
