Using a D* MSPLIT8r1 -02 with Dish

[Miner]

I have one of the D* 1 into 8 Splitters and wonder if I can use it with my Dish setup? I am thinking of using it to blend my Cable (internet and 3-4 channels) into the same set of coax as my Sat and (backfeed).

I figure I would still need to filter out the lower frequencies from the dish using a diplexor, but don't know if I should terminate the unused ports of the splitter. I know that I would be introducing my backfeed signal into the cable line; but since I'm internet only, believe there is an rf choke at the cable head-end. The splitter already has DC power pass to only 1 port so voltages to the other devices isn't an issue.

Thoughts and suggestions?

Direct TV equipment will not work with Dish. Different tech.

Garys,

The unit is a 2-2150 MHz 1 x 8 splitter with dc blocking on 7 of 8 ports. I don't think there is any active functions of the splitter. I'm only thinking of combining OTA, Cable (both sub 850 MHz) and Dish (1200-2150). But I could be mistaken.

Regardless, you DO realize using more ports (8-way split) will cut ALL your signals down a lot - regardless that you are using it as a combiner, nor if/how you terminate the unused ports.
Also, you are most likely going to have problems trying to combine your cable & OTA signals on the SAME coax line; there ARE some freqs that are shared between both types of signals - which is one reason why cable co. frown on people trying to combine OTA & cable signals - EVEN for internet only service. The other reason is the likelyhood of the cable signals bleeding back through the OTA antenna - which does nobody any good!

You're only going to cause yourself frustration trying to use this too large of splitter...if you insist on trying this, at least don't be cheap & spend the few extra $$$ on a proper sized splitter/combiner; it's NOT like they're that expensive...

edit: if you have a dual-tuner DISH receiver, here's EXACTLY what you're looking for:

You bring up some very valid points about line losses. I'm not looking for a diplexor / seperator (although the would clean up wiring behind my box), I'm simply looking to clean up cabling in my access point, tieing my 5 home run Coax cables together with my 2 external connections (cable and sat), minimizing the number of splitters, combiners, ground blocks, etc. I can keep the cable signal separate and run the sat / OTA (backfeed) through a diplexor and then 1 x 4 splitter.

It's not about the money, it's about the challenge of thinking outside the box.

There's going to be a whole lot of notching out of bands required to combine OTA and CATV. CATV is shifting things (including voice and data) around in their band in a fast and furious manner. The problem here is that filters usually take out pretty big chunks of band on either side so you end up burning a few channels for every notch filter you have.

A lot of the HD CATV is up nearer the DISH range than you think and the fact that most OTA is UHF (470 - 698MHz) makes the fit even tighter. The door is probably open for backfeeding if you choose carefully. You MUST make sure you watch out for the cable modem frequencies (DOCSIS 3 can be 5MHz to 85MHz upstream, 108MHz to 1002MHz downstream and you don't get to choose nor can you be assured that it won't change at any time). Somewhere in there is going to be DISH's VERY HOT MoCA channel if you use a Hopper-based system.

A DIRECTV green label splitter probably isn't a good idea. It is not as much like a conventional splitter as you think as it is tuned to enhance cross-traffic and back-traffic on a couple of lower frequency bands.

It is important to note that I'm assuming you're not planning on doing anything as exotic as translating the frequencies.

Interesting comment. From the outside it looks like an ordinary (2-2150) splitter, with power passing on 1 leg only.

Its just an ordinary high frequency splitter with a power passing port.

If only you had X-ray vision.

Have you cut one open?

Keep in mind any part that is connected to the Dish system that neither has a Dish logo nor is a 3rd party approved part will void warranty. Even if one does NOT pay for Dish warranty now, they can put it on and get the benefits, but if any unapproved part is part of the chain, then Dish won't stand behind it. Dish does have a list of approved 3rd party parts. This may not be a problem for some of our members, but this could be a pain to others.

No worries about warranty, all owned equipment.
Now there is some discussion about the actual splitter, I may have to try it, just the splitter.
Back I. The day there were stories of a DPP-44 passing OTA crews to the sat 1 feed so one didn't 2-4 extra diplexors in the area of the switch.
I've always believed there are the specs for something, then there are the 'how it actually performs'.
I might have to break out my o-scope to see what I see, at least what the scope sees in auto mode!

If it doesn't work I might cut it open to see what is in it. Could be fun

Dish Home Protection covers all owned equipment as well, and it stays OWNED. I've had to replace over $1,600 in OWNED DVR's alone, and when I upgraded to the Hopper, I still have my owned ViP's that Dish replaced more than once for me. I shall be selling those soon. So, a big savings on $$$. Remember, you don't have to add HPP until you need it, and then keep it long enough to avoid the $25 early cancellation, or even just pay the $25 cancellation as it sure is cheaper than replacing an expensive STB like the HWS on your own dime. HPP also covers all labor. I know some people here think DHPP is a rip, but for me, all my hardware and labor costs saved far outweigh DHPP's cost. I have come out way ahead, but perhaps others don't have failures, and I can understand that.

Good thought to keep in mind.

I also have a PDI 1 x 8 5-1000 MHz cable TV splitter. It is the same footprint as the D* one, but isn't as tall, measuring about 2-3 mm shorter.

I wish I was back in WA state where one of my lab friends had access to a real time X-ray video system.
