I had my waiver granted to get national feed for CBS and I noticed that I only get it on my HD box, do I have to add another dish? I figure that the national feed stations uses the HD LNB am I correct? Is there any way to get it too my 3 R-10 boxes also? I would like to drop cable and this was the only station that was stopping me from doing so. Or should I just wait till they install the 5 LNB dishes sometime in the next 20 years?
