I have a SWM setup, that uses an HR44 and HR24 dvr. We had an ice storm and I had limbs down on some of my various lines outside. The power did not go out, but I'm only getting the SD channels and (HD channels). Satellite Strength tests confirm low signal strength in 103ca and 103cb and 0 strength in 99s , 103s. What are some things that I'd be able to diagnose on my own towards a fix?
