The 3LNB that you are working with is NOT an HD dish. It is used to pick up 101,110 & 119. Many SD locals are carried on the 119 instead of the 101, as well as some public access type channels. There is no programming on the 110. That dish would be fine with the D12 as long as you are comfortable setting up a multi-sat dish. A round 18" is just so much easier, though. The HD dishes (99,101,103) will have SlimLine written across the front.ctbay said:HD is not a priority. So if I just get a D12 receiver and a single lnb dish then I will get all my programming like at home except the HD channels. Hate to sound like a dummy but I I am not even sure if I have HD service. I know that I have H25 receivers and I tried to hook up one of those today on an old dish. Got message 771A which I found out was not detecting swm. The dish was an 18 x20 oval with 3lnbs and have multidish written on it. I assume that what it was capable of was only to run 3 receivers. Anyway, I was always able to get a signal with Dishnetwork so I thought the Directv would be as simple but not the case. Would have the single lnb only bring in Sat 101?
Someone said get an HD IRD and an AM21 to recieve locals OTA. However, the D12 already has the off-air tuner built into it so the AM21 is unnecessary.
Just get a D12 and some rabbit ears. I'd try the 3LNB 18x20 that you alraedy have and if that gives you trouble, pick up an 18" round. You should be good to go with that.
