I'm trying to put together a tailgating setup and am trying to determine if I can use one of my existing boxes from the house with an older dish that was left behind after an upgrade. I have an older 18" X 20" D* dish that says Multi-Satellite. The LNBF assemply is an Eagle Aspen DTVP3 Triple-feed, Multi-Satellite LNB with a built in multi-switch with 4 outputs. This is the dish I would like to use for a temporary tailgating setup. I don't need HD for this. For a box I can either use a D12-100 or H21-100 (wife won't let me take the HR24-500 out of the house). So my first question is should that dish work with either of my available boxes. I did a quick test with the D12 and couldn't get any signal on 101. I assume that I need to re-run the satellite set up when I move the box to the tailgate dish, but I'm not sure which dish type to select. Several of the dish type options weren't highlighted and available to select on the D12 which leads me to believe that setup won't work. All the dish options are available on the H21. Before I drag out the H21 and start playing I want to know if what I'm trying to do should work and I just need to pick an appropriate satellite type and spend some more time trying to tweak the pointing of the dish or if I need to get a new dish that is compatible with my new boxes. Thanks in advance for any help.
