I have DirecTV in my house. 2 TVs, 2 receivers. The living room is HD, the bedroom is SD.
When going on, say a snowbird run, I take the bedroom box(SD) and put it in the motorhome. My set-up is basic...tripod, dish, strength meter and compass.
I get the coordinates from the DirecTV website.
Seeing mine is a basic...I don't set it up until I'm at my destination. Most cgs have cable, anyway. My setup can take 10-20 minits,depending.
I tell DirecTV nothing....just pay the bill on time. Local channels thru the Batwing...all goes into a passive junction (switch) box. Small TVs (19" or less) don't really need HD anyway.
I do not have, or need, any extra "feeds" ($) like East Coast or West Coast.
