No, C-Band is not. But back when I had a C-Band, Digital was just emerging. There was some sort of modification one could get for the C-Bamd which allowed it to pick up digital channels. In fact, there was a pont in which channels were "dropping off" C-Band after they went digital only and dropped their analog feeds. I started having problems with my C-Band around that time, and as more people were getting mini-dishes, it became next to impossible to get my big dish serviced, and it would have been expensive for that digital upgrade. So, I trashed it and went with DiSH Network. I only mentioned C-Band because they are the only guys AFAIK that did a-la-carte programming.
The signals I get in HD with rabbit ears blow standard digital Dish away, IMO.
What I miss the most about not having the big dish was the wild feeds.
Unfortunately, for me, being 22 miles from the majority of the local TV transmitters, rabbit ears don't cut it-gotta do the outdoor antenna thing for HDTV. Well I can get 2 stations without!
