Dish to Rcvr Connection

[GreenDragon]

I am new to this whole game but have bought the Duo-625 Receiver and Dish-500 with Twin LNBFs to provide Satellite service for my Motorhome. Do I have to run two coax cables from the dish to the receiver? I was under the impression that I only needed one. DishNetwork is most "unhelpful" with helping me.
Also, the "Separator" that came with the Receiver, I assume, is not needed if I have to run two cables.(?)

You need to tell us specifically which "Twin LNB" is on the Dish500. This will allow us to recommend your next step.

depends on the lnb. one cable for dpp twin with seperator.
two cables (no seperator) with dp twin or quad, legacy twin or quad, dp 34sw, or dp 21sw with duals.
a dpp twin will also work with two cables and no seperator.

One cable if it is a DPP twin, it will have 2 out and one in connector on the back. And use the separater
