I seem to have the same problem coming back all the time.I have a 32 inch dish with a motor and switch. I changed the lnb because the plastic protector was cooked. but that did not fix things totally. i still get a jumping signal in bad weather. it is not on all channels and seems to be limited to the h transponders. I think it might be in the wiring connections. Water getting in. just wondering if anyone has experienced this same problem
