Need a little clarification. I have to admit I'm alittle confused with the recent changes. I do installs between lansing and north to grayling but I usually shut down for a few months in the winter. I'm not familiar with the new install formats and it seems like there is some conflicting info floating around.We have been using the SD21 dish. Are we now going to be using the dish1000? Where are the locals coming from if we aren't getting 121? Where do the HD channels come in to play? I also heard that if HD isn't wanted then a dish 500 is all thats needed. Also 129 will represent a line of sight issue in many cases in northern mich. so how is this to be resolved? Thanks for your input...
