multiple splitters - how to daisy chain

Hi, you do not need an additional power supply. One power supply will do. But you can only have up to 8 tuners.. for example you can have 8 regular receivers or 4 DVRs.

The way to daisy chain is as fallow.

Actually the Directv guidelines prohibit more than 8 splitter ports on a SWM dish.  Here is a direct quote from the Technical Bulletin:

You should not use any additional splitters when using a SWiM 8 way splitter on a Whole-Home DVR installation. Splitting beyond the 8 way SWiM splitter may cause the receiver to drop the MRV feature.

You should not have more than 2 SWiM splitters (1 SWiM splitter is preferred) on a Whole-Home DVR install to avoid too much dB loss and potential MRV drop off. If 2 SWiM splitters are used, both splitters must be smaller than an 8 way SWiM splitter.

Do I need to get a SWM 16 multiswitch  (with a new LNB) if I want to go more than 8?   (I have 8 receiveers, but two are DVR's, so it sounds like this acts as 10)

Is this an installation upgrade DirecTV will do for me for the $49 fee, or do I have to manage it myself?

Yes, you'd need a SWM16 multiswitch for the ten tuners.  Directv install is the way to go here, the parts would likely cost you more than they will charge.

How do I enlist Directv's help? Do I need to call, or can I schedule online?

Yes if you have more than 8 tuners you will need to purchase a switch that will allow for more than 8 tuners like the SWM16 or SWM32.

Now you will also need to change your LNB, the SWM LNB you have will not allow you to add a SWM16 multiswitch.

You will need to get the SL3, or SL5 LNB as well

As far as cost, you will be looking at around $330 if you were to do it yourself.

Call.

Great - thanks. I called them and had to add a receiver through them to get an installation tech scheduled. I told them to put in the notes that I would like to upgrade the LNB and add a SWM16 multiswitch - hopefully the tech comes prepared!

if by adding that receiver puts you over the 8 tuner limit, DTV's automated ordering system will add the SWM16 switch automatically.  the CSR's can't add support hardware.

Why does any one need 7-8 recievers in one location in an average home?  8 locations within the home is bad enough.

It all comes down to the NFL. To watch all the NFL games at once on Sundays during the fall you need 8-9 receivers in one room (the 1pm Sunday timeslot usually has 8-10 concurrent games).

Ped48_installs: quick question - is that counting DVR's (even SWM DVR's with one coax input port) as two receivers? So if I have 2 DVRs and 5 other HD receivers, this will trigger the SWM16 in the ordering system?

Yes.  It's based on number of tuners. DVRs have two tuners, Receivers have one.  SWM8 = 8 tuners. SWM16 = 16 tuners.
