I have a job that keeps me away from home (260 miles worth) for two weeks at a time. During my time away I live in company provided housing. It comes with standard def Direct TV. The dish for this setup is an 18x20 with triple LNB's pointed at I believe 101,110, and 119. At home I have an HR24 and a Slimline dish pointed at whatever birds are used for HD programing (sorry , I'm at work right now so I cant pull the setup menu to see exactly which birds). I would like to carry my HR24 to work with me and hook it to the 18x20 dish. I would disconnect the standard def receiver that is on the company account and hook my HR24 on my personal account in its place. This would give me the DVR function which would be really cool. I know that I would probably not get any HD but I dont care becuz the TV set is an old 480 CRT. Does this sound like something that is doable. I know I would have to change the dish designation in the setup menu. My other (expensive) option is to mount a Slimline next to the 18x20 on the roof. What do you think?
