I'm guessing that this means two are being fed from the first. This is way more loss than you need to have.
I'd have them come back and use "smaller" splitters to gain resistance against rainfade.
The SWM output and the receiver's input levels shouldn't have more than around 25 dB of attenuation and an 8-way to an 8-way eats all of this up and some more, so you've lost all your "system reserve" for weather.


Unfortunately, some out there still think that in order to have 5 to 8 TUNERs you need an 8 way splitter. This goes from installers, to stupidvisors to trainers (oxymoron).

Sometimes, you just can't fix stupid. :nono2:

First: it working now and that's good.
Second: it would be better to get away from 8-ways to 8-ways as I posted ^.
"The best use" of an 8-way is one that has all the receivers connected to it.


Yeah, I may be put the non-green label 2 and 4 ways back on. I've got a busy few weeks, so I'll at least get to see how well (or poorly) this set up works.

Yeah, I went through this with the trainer who came out here with the engineers a while back. He saw my Skywalkers and offered/wanted to swap them out for "DirecTV approved" ones, but only had 8-ways with him.
A five min discussion between me, the trainer, engineer and my skywalkers stayed for "a good reason" and the trainer hopefully learned something.

FYI: the 90% readings are more quality than RF level.
As the signal at the LNB drops, the SWiM will add gain to keep the output @ -30 dBm. when the input drops below -45 dBm, then the SWiM is out of gain and the outputs starts dropping. The receiver wants -54 dBm, so the less loss between the SWiM and the receiver, the longer the receiver will have a usable input signal.
I would care more about this than whether my splitter had a green label [DECA approved] or white label [SWiM approved].

I'm in Snellville and scheduled for this evening. (Twiddling my thumbs right now.) I'll let you know how it goes.


DogLover, how long did your install take? Did they have to replace your dish?

The did replace the LNB with a SL3, but not the dish itself. He removed the old SWM-8, added the DECA modules to the non-24 boxes, then realigned the dish to get great signals on all satellites. It took about 2 hours, maybe a little longer.
