Well new dryer hooked up and still loses signal! I just knew this was going to take of it. I don't mind so much buying the dryer as other was pretty old. Time to have Dish move the dish I guess.
Remember all coax is not created equally either.Coax is shielded. So I wouldn't be too concerned with that. But EMF can be introduced by the electrical supplier. And Robert is correct. Most appliances are designed to operate normally with a +/- 10% voltage deviation. And, I would hope that the dryer is on a fixed double pole breaker. Not 2 singles.
