How could this work, two dishes and 1 OTA antenna? Diplexer

[ZandarKoad]

Ok, I have edited the drawing, but I think this is the schematic as needed, correct? (What can I say, I was bored at work and am very anal.) Sooo, does this look right to all of you?

Actually, by the satellite, you have the antenna side leading to the satellite. The diplexor by the satellite needs to be reversed.

But more importantly, you don't have any doodles to distract the viewer.

Oops, how's this?

Excellent!

Ok, whats a satellite splitter and how is it different than a diplexer?

Also, ZandarKoad, is that a frog?

 

[ZandarKoad]

lol, yes it is. I forget where I found the pic. I just thought it was funny.

Well, I've never personally used a satellite 'SPLITTER'. That could simply mean a standard high frequency splitter used on a single LNB feed (for E*, it only works with Legacy I'm told, I know nothing of D*) to split it up. You can't split satellite feeds (using conventional equipment) that have been stacked (stacking occurs inside switches). But E* has their own proprietary equipment called "DPP SEPERATORS" that they use to do just that. So I'm not exactly sure what you mean by satellite splitter...

But a diplexer will take two different frequency ranges, and put them on the same line. A "satellite splitter" doesn't differentiate between two seperate ranges.

My knowledge is fairly rudimentary, so feel free to correct me here if I've slipped up.

Yeah I know you can't split satellite feeds. But in bertbarndoor's diagram he placed "satellite splitters", where in fact you could just use a common two-way cable splitter. So, I did a search for satellite splitters. Sure enough, they exist. This particular website(can't remember now, it's been more than 24 hours) had a description of the things that sounded exactly like a diplexer to me. I was just wondering if there was a difference, or maybe it was just a cable splitter with HF input/outputs. Who knows.

But man, is that frog huge.

 

[ZandarKoad]

Ah well. I believe it. I imagine different terms can mean different things depending on who you talk too.

I agree with ZandarKoad on his last two posts, but here's my 2 senses.

As said, the diplexer will combine 2 separate freq ranges on one end and then (cleanly?) separate them on the other; while the splitter will route the same signal/signals to multiple locations, but some splitters could be used to combine multiple RF inputs of the same range into one input (but probably not very effective in most cases).

Although bertbarndoor shows "satellite splitters" in his diagram, I believe what he really needs is a regular splitter with a frequency range to cover the UHF PRO Remote (400 - 500 MHz) and whatever TV/Cable channels he will be using. A 5 - 900 MHz or 50 - 1000 MHz for TV antenna and/or cable use should do it.

I guess satellite splitters would refer to those that operate at least in between 950 - 1450 MHz, including 50 - 1450 MHz (+/-); as well as others which have a high end frequency range somewhere between 2150 MHz - 3000 MHz. http://www.amabilidade2002.com/splitter2.htm
But I agree, call it whatever you want it is still a splitter.

However, some splitters have DC passing/blocked on various ports for use with satellite equipment. Some splitters not designed for satellite use may not hold up well to the power being supplied to the LNBF. Also, some cable systems are two way, and any splitter used in such a system would have to support it (similar to/as the Eagle Aspen Home Node).

That said, there is a DishPro Splitter. I believe it may be used in multi-dish/multi-receiver installations, and also when first setting up the ViP 622 when using a single cable from the DPP-44 (although setup can be accomplished without it).

Ah, I didn't even really notice that. You're right, the "Satellite Splitters" in those locations on his diagram is way overkill. Not only are the frequency ranges way beyond what he needs, but both ports are also power pass! He doesn't need power pass, and he doesn't need any frequencies over 1000 MHz for those two spitters.

None of this is to say that his diagram is wrong, it's just much higher quality than you really need. :up
