I have an outside antenna that comes in to my Hopper and have generally always been able to get reception on several channels. The last couple of day it has shown "no signal" on two of the seven channels we watch. This happens all day and night. The TV in the bedroom which is not on Dish receives these channels just fine. Any ideas what to check? I know I have a Dish OTA adapter that was installed about 2 years ago. I have not checked the connections yet. I live in southern Michigan and the weather people on tv have been talking about the smoke from the Canadian wild fires overhead. Would that possibly affect reception on only two channels? Just looking for some ideas. Thanks in advance for any advice.
