We have a Winegard carry out dogs and its done well for 4 years, until now. Checked power cord and its working, cable good, new receiver. Test by Dish network tech onsite says it's not picking up satellites. Next thing, in the morning when it's cooler,, is remove the dome cover and check for a blown fuse inside, or other more expensive problem. Hubby NEEDS to keep up with his team, OKC Thunder, this fall! Does anyone have any input on an issue like this? Seems pointless to lock ourselves in to a roof mount when we actively seek out shady campsites whenever possible except winter.
