Loop Through Wiring - Options?

[ZandarKoad]

Is the new SWM13 switch the ONLY device that will work with loop through wiring (taps)? Or is there a 'lesser' switch (one with 8 tuners on a leg) that will still work with loop through wiring?

I've got a layout where we have some legs with 6 tuners, some with 7 tuners, 8 tuners, some with 9, and some with 10 tuners.

Also, isn't there some device that allows you to utilized un-used tuners on a SWM13, for example? Or does that device only work with SWM16/32 output ports? I heard talk of one, and can't remember the name.

Thanks.

Swm 13 lnb does too. But these are the only dswm items available.

Any LNB or multiswitch will drive loop thru with taps. But the SWM13 multiswitch has a much higher output than the other devices so will support more drops. You can calculate the number of taps that a device can support using a standard loss model.
By the way, I'm pretty sure the SWM13 LNB has the same output level as the other LNBs so is no better in a loop thru situation than the SL3S or SL5S.

Not to argue with you but dswim items are the only product that directv will support loop through wiring. Not saying it won't work... but this is how it was designed.

Not arguing with you either. I was talking about what will work, not what is supported. The secret to supporting loop thru is using taps instead of splitters, but with older multiswitches the output is not high enough to support a long multidrop loop. The difference between a tap and a splitter is that the splitter (two way, for simplicity) has two equal outputs. A tap only "taps off" a small part of the signal, leaving most of the signal to move on to the next tap. One big advantage of using taps is that the input signal can be MUCH higher than with a conventional splitter system, since each receiver only gets a small part of the signal. That's why you can't just use the DSWM13 in a conventional residential installation because it could overload the receivers.
That's also why the SWM13 LNB (not the multiswitch) will be no better in a loopthru situation than an SL3s or SL5s LNB, because it does not have the "hot" output.

By the way the "D" part of the name (as in DSWM) does not relate to this at all.
