    Okay, now I'm confused again. Can an SWM-16 run with only a single input line? Even to power just 8 (or whatever) TV's? Or does it require 4 lines to work?

    Assuming I just wanted to get "something" working with the single line, are those my options?

    - An SWM-16 with one line to power 8 devices
    - An SWM-13 with one line to power 13 devices

    I just heard back from the homeowner, they do want to add DVR's at some point. So in order to use a DVR with an SWM-16 I would need to find some way of running three additional lines from the satellite dish into the basement of the house?

    And this last question is going to sound dumb to you guys, but how do I know if the satellite dish even has four outputs? Is that standard? I.e., if I climb up on the roof am I going to see three extra ports next to the one that's running to the basement?

    Gaah. Looking at a picture of an SWM-16, it looks like it has four ports for "input": 18V, 13V, 18V/22KHz, 13V/22KHz. Does it matter what plugs in where? LOL, why can't it have a single, clearly labled port for "Input"? I know, dreaming again! ;-)

    It can't have a single input because the SWM16 requires four lines for full DIRECTV service.

    The current dish has a built-in 8 channel switch. It's capacity CANNOT be multiplied or split.

    There is a 13 channel assembly that can be fitted to the dish and that is currently the absolute maximum for a single coax. Again, it cannot be multiplied or split.

    As doctor j recommends, now is the time to drill as ultimately they are going to need more cable coming in from the outside (unless you can convince them that downloading and streaming to umpteen TVs simultaneously is a reasonable alternative).

    Well, I've got an SWM-16 on order, an SWM13LNB, two 8x way splitters, and no idea what I'm doing. ;-) The other downside is this project is 125 miles away from my house (the things I do for friends!), and I was trying to avoid making any more trips out there than necessary.

    So then I guess these are my options:

    - Bring a chisel and figure out how to get three more wires into the house, build a shelf on the rack containing an SWM-16 and the 2x 8-way splitters, connect all 16 lines to the 8-way splitters, the homeowners would be able to use up to 16 receivers, 8 DVR's, or some combination of the above.

    - Climb up to the roof and replace the "LNB" (?) with the SWM13LNB that I read about by googling. ( http://forums.solidsignal.com/showthread.php/6837-Solid-Signal-s-HANDS-ON-Review-DIRECTV-SWM-13-LNB ) Use the existing single wire into the basement. Connect a splitter at the end, and then run that into the 2x 8-way splitters on a shelf on the rack. I assume I could still plug in the 16 wires (terminated at the ends of all unused lines), but homeowners would then be limited to 13 receivers, 6 DVR's, or some combination of the above.

    I am getting a whole DirecTV education! :)

    You will not use the SWM13 LNB with the SWM16.
    Here is a sketch compliments of Solid Signal that shows how to wire up the SWM16.

    Not a good idea to have a 2 way feeding two 8 ways. Given the size of the house, the loss would be to great.

    No, I'm saying the heat output of a SWM16 that consumes 17 watts is identical to that of an incandescent light bulb that consumes 17 watts.

    I suggest you wait to do anything else till you truly understand what and how this all works, because as others have noted, you've ordered equipment that isn't all compatible with each other. I would also not mount a swim 16 and try and simply run a line to each room. You only want rooms connected that are in use, you have to terminate all unused ports, so its easier to use smaller splitters and have better signal, and not terminate as many ports.

    You are trying to set this up like a distributed cabel system, and you do not want to do that. Not at all. This takes a little more care than that.

    You must run IMHO for a house this size with this many possibility four lines to the main room from the dish. This gives you all options, without it you are very limited at this time. Maybe you can get there a different router than the one cable that has been run? You said its in a basement, how about coming down outside (behind or even inside a rain gutter perhaps so its not seen, I have even see a rain gutter installed once just to hide the lines) and then inside to the room? Where there is a will, there is a way.

    Once you do that, I would then install a swim 16, one only, and stop there. Use only the splitters you have to to connect what they are using today. If they only have two locations, you use a two way splitter, not a 8 way. And make sure you do not go over 8 tuners on either of the swim16s outputs. When they get to the point they need more than 16 tuners then you can do some other things to get above 16, if they ever actually get there. But all those options lower the signal levels a little, and there is no reason to do this unless you actually need it IMHO.

    One thing I am not sure has been explained to you is, its all about tuners, not devices. The swim16 can connect any number of devices as long as each of its two outputs never go beyond 8 tuners. You could connected more than 8 devices though, depending on how and what they where, like bbdeca devices and clients.

    There is also a deca node limit which is 16 for any one deca cloud. This is easily overcome in your situation though since you are at a major Ethernet area, so you can simply create multiple deca clouds and join them together right there. Deca is how directv pushes mrv and internet across all its devices, so there is only one internet connection point into the system. Deca basically allows them to run internet and such over the same coax as their sat signals. For a lot of reasons, its better that way and keeps their stuff generally segregated from the rest of the system.

    It does appear that you are out of your depth and are going to cause your friends more issues than help them. Any professional who figures their clients are going to pirate shows as a legitimate and viable setup is scary for too many reasons to go into. At the end of the day do what you know and tell your friends to contact someone who knows what you don't. It's a better way to keep friends.

    I somehow doubt that is true.
    Just because something is the same wattage doesn't mean it puts off the same amount of heat.

    The swm16 non the less isn't that hot to the touch.

    My son installs those window rattling audio systems in cars. He says that amplifiers that are under powered get hot and burn up. If they had the proper power the heat goes down. One guy did not believe him and wound up installing his own system. The amp burned up and caught the car on fire.

    I do not know if the usage per watt is relative to the heat build up, but I do know that I can touch a 13 watt light bulb ad not get burned and if I touch a 40 watt or higher I get blistered.

    I guess you don't understand how electricity works then. How do you think a SWM16 should be able to give off more heat than the power that is put into it?

    I suspect the problem was not the amp heating up, but rather the power cords feeding DC power to the amp being under rated and overheating. At 12 volts, you are dealing with some very high current ratings.

    He puts wire in the installs the diameter of you little finger.
    That guy that burned his up used something half that size or less. The other thing they do is put a bigger alternator and add a second battery to keep the voltage from dropping when it hits hard on the amp.

    Yeah. He didn't use heavy enough wire. It's also why I cringe when someone says the blanket statement of lamp cord is just as good as any other speaker wire and cheaper so use it to drive your speakers. It's just not true for everything. Heck for most things.

    If I remember my basic college phizzies correctly, the amount of heat energy a device generates and the actual rise in its body temperature as a result are different things.

    You can have two devices generate the same heat energy, but their temperature to touch depends on the thermal capacity of the structure serving as the heat sink and the ambient temperature the device is operating in.

    Even with power injectors on both lines? Tentatively this is now my new plan:

    [​IMG]

    I need to actually figure out where the antenna is, and see if I can get up there and change whatever's up there for the SWM13LNB. I'm actually planning on making a rack shelf now that has the 2x way splitter, the two 8x way splitters, and also a SWM-16, the power supply for that (which I'll leave unplugged at first), and the two power injectors for the two 8x way splitters. I'm going to mount that in the bottom position of the rack, then directly above it I've got a 4-fan unit to install (basically a fan system intended to blow air through server racks).

    I figure I'll operate it like this:

    - Connect everything from the SWM13LNB on down through the single existing coax line. Plug it in like the above diagram, and explain to the homeowners about the limitations of this method. Then if, at a later date, they decide they need more TV's, they can swap back to a standard four-output LNB, pay someone to chisel the three additional lines through their stone walls, swap the plugs to the SWM-16, plug in the fan to cool it, and be good to go.

    Basically I'll give them enough to get them running with several TV's, with the option of expanding the system more further on down the road, all built into a nice, rack-mount shelf.

    This is waaaaaay more complicated than if they just went with Comcast cable, haha. :p

    You shouldn't use power inserters unless they are needed.

    Will they be using more than eight rooms immediately? If not skip all that and at most connect one 8 way splitter from the dish. I hope you read my post and understand about terminating things and not using more splitters than necessary etc.

    And if your ok carefully you would realize that system shown only actually needed one eight way splitter. It was just an example.

    The design of it makes a big difference. Even if the core is the same temp as a 15 watt bulb, the outside by design the swm 16 would be cooler to the touch than a light bulb.
    Swim 16 has raised ridges that promote cooling. A light bulb doesn't.

    I am a machinist by trade not an electrician.
    The larger weight of metal will hold the heat better than the light bulb. The thin shell of the bulb makes it throw off all the heat generated. To test this you could turn them both off for a specified time and then check the temperature of each item. The bulb will cool off almost immediately and the SWM 16 will stay hot for a long time.
    Without the cooling fins it would stay hot even longer.

    Having said that I was just studying AC window units and there is a direct correlation between the wattage used and the BTUs put out by each of them.

    Why doesn't someone that has a SWM 16 test it for temperature and then do a 15 watt light bulb so we will all know what the real answer is to this argument ? You probably need a laser temperature gage also to check them with.

    Also rumor is and more than likely true is that a new Swm lnb version is in the works that will do more than 16 tuners down a single cable, if and when that is released it would just be a simple lnb swap at the dish.
