-Standard definition programming really only requires the 110/119 using a DP Twin Plus.
-Eastern Arc installs would use the 1000.4, which uses a DP Plus LNB as well I think.
-High Definition programming elsewhere would probably use a 1000.2 dish, which has a DP Plus LNB.
-You can also pick up the 129 or 61.5 for HD programming using a second dish with a DP Dual plugged into the DP Twin Plus input port.
With any of these setups, you MUST have one RG-6 coax sweep-tested to 2.25 GHz or greater running to EACH dual-tuner receiver.
edit: This is what I found that is most like what you're looking for.
