My father inlaw has two dishes with a single lnb on each. Those both go into a sw21 splitter and then the one single coax going into a dishpvr512. My problem is that I have upper channels but not channels from 2 to 70. When I do a check switch it shows 129 and 119. I'm really confused as to what I need to do to get my local channels back. This all started because he moved them about 20ft straight from where they were originally installed. Any help would be appreciated. The zip code I'm setting these at is 69147. I think I need a dish on 110?
