For the DishNetwork music station you will need a circular type LNBF. This is the type that DirecTV and DN use. You will need to setup the L.O. frequency for this LNBF in your reciver to 11250.
For the other FTA channels on
Telstar 5, etc. you could use either a Universal or Standard type LNBF.
You will need to connect the two LNBF into a 2-way
DiSEqC switch such as the one found here:
