Has any one used the Directv green splitter with dc pass thru for OTA ?
I've been known to do some things that I shouldn't.
The Green splitter has another circuit [for DECA] that doesn't work with OTA.
Just because you CAN do something doesn't mean it is a good idea. You can also use an ordinary cable/antenna splitter for SWM. Neither are optimal, and when the real thing costs about $3 off eBay there's no reason you should do so any longer than the few days it takes for your eBay order to arrive.
That's why I asked. I have both kinds splitters but with OTA Digital freq. change, I thought maybe the Directv splitter would be better. Its good to know its not.
"This" is why:
MRV uses the DECA networking
Good to know
Wow that would take a huge chunk out of our DOCSIS spectrum if it accidentally mixed with our cable feed.
Actually probably not, as almost all cable systems use that part of the spectrum for QAM video, not DOCSIS. DOCSIS is generally at the top end (over 750 MHz) and very low (under 100 MHz) of the cable TV plant. But yes you definitely can't carry cable and satellite on the same coax, they overlap and neither will work.
Its depenent on cable company though. My modem at 192.168.100.1 shows 16 channels downstream ranging from 543 MHz through 663 MHz, and 4 upstream channels ranging from 23 to 38.5 MHz. I bet if you accidently mix CATV and DirecTV you would blow away the upstream too since thats so noise intolerant and sensitive.
Though not a DOCSIS 3.1 modem, I can clearly see a contiguous 96 MHz block (OFDM) compared to the smaller 6 MHz QAM humps on the spectrum analyzer. Almost our entire spectrum asides from maybe 3 or 4 6 MHz blocks are used up from 110 MHz to 860 MHz.
Yeah that's true, I guess some places haven't upgraded their cable plants so they have cut out channels to make room at lower frequencies. Likely isn't even consistent even with the same cable company, as different cities have different build outs.
My modem status page shows 32 256QAM downlink channels from 471 MHz to 663 MHz.
The four uplink channels (DOCSIS2.0 (ATDMA) 5120 kSym/s 64QAM) are below 50 MHz.
