When you have an installation from Directv, the work order will run the required number of cables from dish to receiver to support your installation.
If you start with 4 receivers without DVR's, that requires four lines for 4 tuners. Which a 5LNB handles. But if one of the receivers is a DVR, you will probably get a WB68 8-port multiswitch.
If you end up with a multiswitch and have ports available you can add more recievers later and hook them up yourself. Could you use the existing wall jacks, maybe. If the cable is RG6 and not RG59.
Now to complicate matters, there's a product in this Installation thread called a SWM. That can use RG59 and no multiswitch is required. But it's not likely you will get one at install. They are few and far between.
If you are a new customer, I recommend you work out a deal for the most receivers and install up front. Current generation receivers and DVR's aren't that much of a bargain on ebay. You still pay $5 monthly fee on every receiver anyway.
