    A SWM LNB would appear to the best option here, BUT - -

    Did you notice back in the original post where the OP said he would support 4 TVs at each end of the house? Meaning a possible total of eight receivers, someday? Did I read that wrong?

    True, he only ordered 4 receivers from D* at this time, but if he goes ahead with the SWM LNB, he is not going to be able to support all those locations, eventually. He's going to run out of SWM channels.

    Maybe he should consider two SWM LNB dishes, one on each end of the house.

    Please review and advise if this routing would work. Each leg would have 1 each HD DVR and 3 each HD receivers.

    That look fine as long as you never have more than eight tuners [DVR = 2] total on the system.

    Current SWM devices can support a total of 8 tuners (with a DVR having 2 tuners). So your proposal to have 2 HD DVRs and 6 HD receivers total results in a total of ten tuners. Thus a single SWM dish or multiwitch won't serve your needs.

    The option is to install two SWM8 multiswitches, one to feed each end of the house. That would support 8 tuners on each leg, which would not only serve your current needs, but also would allow room for growth (perhaps replacing a receiver with a DVR in the future, or adding another tv location).

    Unfortuantely, DirecTV is not going to provide this. It is something you would have to absorb the cost for.

    A second option would be to have two Slimline SWM dishes, one for each end of the house. That would give you the same capacity - 8 tuners on each end of your house. It is possible you could get that out of DirecTV.

    With D*'s new rules relating to SWM they should upgrade a SWMLnb to dual SWM8's or a SWM16 (when eventually released) if the tuner count justifies. There would be no point for D* to install a SWM8 for everyone just for "possible" future expansion, it's simply not cost effective... Since the OP ordered 5 tuners (including HD DVR) a SWMLnb should be generated on a workorder. I don't "think" anyone really wants two dishes installed on their home...

    This is no longer true, although in short supply, SWM8's are authorized for use in residential installs by techs. This is subject to supply restrictions however (and supplies are very low...)

    Realistically, I should never need more than a total of 8 (unless my kids move back home) But if each split can support a DVR and two more receivers, I should be good to go with the single SWM scenario. No word today from the installer.

    What you have in your current diagram should be fine. However, you won't need two 4 way splitters. You can use a 3 way splitter as you will only need 1 wire going to the DVR's (although it will still be feeding two tuners).

    Do you really mean for the cable length to say less than 1 foot between the 2 way splitter and the top 4 way splitter?

    Also, it's a Power Inserter (not inverter).

    I hate 3-ways so much, I'd either terminate the unused port of a 4-way, or simply use 2 2-ways [since this is all a 3-way is].

    UPDATE - Original installation is cancelled, deposit refunded.

    Yes, I did mean only 1 foot between the splitters. Still thinking CATV I guess. I updated the cabling layout (rev 3A). Please let me know if this is cleaner. And now that my original installation is cancelled, please advise how I should proceed, locating a competent installer.

    Thanks

    I would swap the legs. You seem to have short cable runs off the 4-way and then longer cables & splitter off the last port of the 4-way.

    I'd feed the additional splitter on the short runs off a port on the first 4-way and then connect the long cable runs to the other ports of this 4-way.

    You want to try to balance the losses on all legs, so the receivers all have the highest signals you can.

    In your area there are companies who do Home Theater work or antenna installations. All these companies were at one time approached by Directv (my guess) to conduct their installations. They have a great mass of experience....but for one reason or another...will not continue within the Directv system. This is the way both parties want it. Present your project to contractors with a specification and a request for bids. Look at how the bidders plan to do the work, how long will it take and evaluate the prices.

    Without speaking for Directv, the FREE installation was never intended to be more than a process to establish a signal and get a few TVs running. Anything beyond that is a stretch.

    You have a Ferrari Enzo..............do you take it out to the end of the driveway with a sign..."WILL PAY CASH FOR A REALLY GOOD TUNE-UP" or do you find someone with years of experience, a shop with employees and the ability to continually serve your needs?

    In fairness.......the FREE installation is not everything.

    In your diagram, what cables already exist? Is it just the one bottom one that will connect the 4 way splitter to the 3 way splitter?

    If the cables are already run, from your current CATV installation, this should be an easy install using SWM. If the cables need to be run, going with a custom installer would be the best way to go in order to get what you need.

    Bill, all of the cables are already there (in place). All are new RG6, identified on the package as used for satellite installations, purchased at Fry's electronics, except for the 50' to TV 1. That is a piece of Comcast cable.

    Guys, I would like to do as much of this as I can on my own. I would like to better understand the self installation side of this, i.e. what I can buy and install, setup myself. Any advice and direction is appreciated

    You could certainly do it all yourself. All of the necessary parts are readily available on sites like www.solidsignal.com (many also use auction sites to get them at a fraction of the price.) You don't have to go to the extreme of full DIY though. At this point the only thing that's holding you back is that you'd like a SWM setup correct?

    If you're happy with an 8 tuner limit why not purchase a SWMLnb, PI, & SWS splitters and schedule another install? When they arrive hand them the SWMLnb and ask that they install it instead of the legacy unit. You already know what to do with the PI and SWS splitters.

    BTW, there's also a good chance that when you schedule another install you'll get a tech who's SWM knowledgeable and has the parts necessary. Personally I'd try that route first since you DO qualify for a SWM setup according to D*'s own rules. Whether the local wharehouse has SWMLnb's in stock could always be a factor...

    That's exactly what I did this summer. I found a SWM-LNB, PI, and splitter on ebay real cheap (around $30) and bought it. The previous owner had an old round dish pole mounted in the back yard with two lines buried running to the house. One line went into the basement and was easily acessible. When the installer showed up I showed him the old dish, and the line in the basement, and then handed him the SWM stuff and said this should make your job a lot easier shouldn't it. He smiled and said thanks. He was glad to install my stuff as it saved him a bunch of work trenching in the other lines he would have needed from the dish to the house.

    You can buy it all if you really want to.

    Dish

    Power Inserter

    SWM 4 way splitter

    Power Passing Splitter

    However, it really shouldn't be necessary. Your current cabling is exactly what SWM was built to accomodate. Any competent installer should be able to do what you need as part of the free basic installation. There's nothing complicated or difficult here.
