Talking with Dish I thought they said I'd be able to get local channels (such as Los Angeles Local major networks) even if I was not physically in the LA area. I'm not sure that that statement is 100% accurate. Need to do more research. We spend a LOT of time in places like remote Alaska, Canada and the remote deserts in Arizona, New Mexico and West Texas. DirecTV has NO or very few local channels in those areas. If I understood Dish correctly I could call them and tell them I wanted to switch to the LA locals and I could get the LA networks anywhere I could receive Dish transmissions. None of the limited footprint nonsense that DirecTV has. I also know just from reading the RV forums that changing locations on Dish is very easy when compared with trying to change locations in DirecTV.
For all those who recommended specific hardware, thank you. It sounds like Hopper 3 might be what I'm looking for. I talked with the RF Mogul folks this afternoon and they said they had more than one arm/LNB combo that would receive Dish, but if I knew which receiver or recorder I had they could better recommend the highest performance antenna head for that receiver. Research continues - - -
