Here is what I read.
“How can you upgrade to the Hybrid dish?
Start by getting the Eastern Arc Hybrid (Slimline) LNB if you’re on the right side of the country or Western Arc Hybrid (Slimline) LNB if you’re on the left side. It’s very easy using a screwdriver to disconnect the old LNB, disconnect the cables coming from it, and reconnect the new LNB. I usually mark the position of the dish’s aiming bolts (found on the back and bottom) with a marker or pencil to make sure I don’t accidentally move them.
If you have only one cable coming out of your dish, this is the easiest option. However, if you have multiple cables coming out of the dish it is usually easier to upgrade to the DPH42 multiswitch instead. This multiswitch gives an older dish Hybrid capabilities and it can often be an easier install. With a DPH42 you don’t need to know if you need an Eastern Arc or Western Arc LNB. You’re leaving your existing LNB in place.”
Here is a photograph of my switch hookup.
