    I apologize if current info is on the forum already but I can't find any.
    Install is scheduled for Friday (changing from Dish) and we will have 3 DVR's. Currently I have two RG6 from my Dish into the house and adding anymore will be a nightmare if I can have my Directv dish where my current dish is. Can anyone tell me how many cable drops into the house are needed for 3 DVR's so I can start figuring things out. I'd rather get a handle on it now rather than have the installer catch me blind on Friday.
    Thanks

    As few as one. With SWiM, each DVR needs one coax connection. Where do the two coax cables terminate in the house and where will the DVRs be?

    If you go with a SWiM [single wire] you'll get something sort of like this:

    It could require 4 cables if you don't get a SWM install. If you are getting HD equipment you will most likely get a SWM install which will only require 1 coax cable running into the house, then it would be split from there to run to the 3 DVRs.

    One cable would be awesome. The dish is on the far side of my garage wall and the cable drops go into the basement. To get the coax to the basement they run above the garage ceiling and down an insulated wall into the basement. It was easy before I drywalled the garage thinking I was done and could close it all up. If one cable drop would handle the three DVR's, adding a switch in the basement and distributing the individual lines to receivers is a piece of cake.

    Based upon what you say, I'm almost positive you will get a SWiM install using one coax to the basement and a splitter there to run to the three DVRs.

    And then :welcome_s to DIRECTV. :)

    Cheers,

    The switchgear is in the LNB assembly.

    Don't mess with/repurpose the second coax coming in as you'll need it if you go to more than 8 tuners.

    Thank you very, very much. All the switches are foreign to me because Dish doesn't use any to my knowledge but I think I already figured out the SWM is Single Wire Multiswitch :)

    The only "switch" you will get will be incorporated into the LNB on the dish (the Single Wire Multiswitch technology). Exterior to the dish, at the other end of your coax run, you will have a splitter with coax going to each DVR/Receiver location, as well as coax going to an internet connection (if part of your install). You'll also have a power inserter (per the illustration VOS posted).
