Switching Dish to SL3

    I have looked through the threads but can't find specific info on my situation.

    I have a Slimline 5 dish with three HD receivers located 1 upstairs, 1 on main floor & 1 in the basement. The wiring is all run on the outside of the roof and then drilled into the 3 rooms directly.

    I went to replace 2 of the receivers with 2 HR24 DVR's.

    Can I simply replace my SL5 dish with a "SLIMLINE HD DISH KA/KU 3 LNBs / NEW SWM / MRV". LNB is a DTV SL3S4R2-01. Power Inserter & 8-way Splitter.

    Am I correct in understanding that I would need 5 wires from the dish, or is the splitter used inside?

    I think I read in one of the threads that with the power inverter I only need one line to the DVR rather than 2, but I couldn't find more info.

    Thanks very much for any help.

    You could just replace the LNB and use the existing dish (you probably won't even need to realign it). The power inserter should be located inside and the splitter can be also, so you would only need one wire from the dish.

    This question probably sounds really dumb, because it sounds dumb to me, but does your answer mean that I can just run one of the existing lines into the inserter and splitter, then into a receiver and they will all work, or do I need additional wires coming out of the splitter to each receiver?

    Thank you

    You would put the SWiM LNB on the dish. It has one coax connector which would run to a splitter. From the splitter, you connect the three coax that are currently run to the three rooms. Whichever coax is connected to the power passing port on the splitter you put the power inserter on at the tv location.

    So, one coax from LNB to splitter. One coax from power passing port of splitter to power inserter, then from PI to receiver. Coax from each of the other ports to the other receivers.

    Assuming your current coax from the dish goes to a ground block someplace before the coax goes inside the house, you can put the splitter at that location. Make sure you get the correct green-label splitter for DirecTV use.

    Keep in mind if you switch from a 5lnb to a 3lnb, you may lose your SD locals depending on the market, a handful of religious and music channels.
