Do you have a SWM or multiswitch LNB on the dish?
If you have a (multiswitch) LNB dish, you will need to run two separate coax feeds from the dish using B band converters at the HR24 receiver. If you only want to run a single coax you will need a SWM LNB on the dish, power inserter and SWM multiswitch installed in the rig. About $100 investment to swith to SWM. I am in the planning stages right now to put SWM in my rig.
I'm looking forward to feedback here as well.
