Options for wiring signals

[Mike_H]

Looking to do some wiring this winter in the house to get the rooms setup. I'm adding a digital tv antenna and adding a 622 to take the place of a couple receivers.

Now I want to back feed the RF out from the 622 for use in other rooms. So what I'm wondering is can I have just two coax lines to the 622 using a DPP seperator, and combine the signal from my digital tv antenna onto that with something like the Perfect Vision PVDP2 diplexer ?

Then stick the RF out of the tuner 2 on it's own coax back out?

Is there room on the dpp seperator to combine that signal onto the line?

i.e. signal from lnb sat1 + lnbsat2 put on one line with a DPP seperator, then take that as a sat into the PVDDP2 diplexer to which I add the digital OTA antenna, giving me one wire up to the 622, that I then split out with another pvddp2 diplexer, and then a dpp seperator to go into the 622.


Thanks.

I am having a hard time trying to understand what your saying exactly.

DPP Seperator is used behind a dual tuner receiver, the purpose is so that you can run one line from the dish to the box.

Here is a couple of diagrams that should answer your question.

Sorry, it was a bit confusing for me as well.

The diagram helped. DistributionExample7 shows what I'm talking about, with using the Plus system, or at least shows me what I needed to know.

thanks

More questions. From the Distribution example 4 it has me questioning if the output from the 622 agile modulator can just be combined into the antenna line, or something like the super home node is necessary to inject the output of the 622 onto the line.

What I want to achieve looks like this. So the ant, plus the output of each 622 is available anywhere along the RF chain. Will this work with just splitters used as combiners? Is there something else needed for the 622 output?

Let's break this down...

On all of your spare tv's you would like to be able to view tv2 from either of the 622's, plus OTA?

Yes it can be done with two-way splitters used as a combiner... thing is you need separation between the channels. Your likely to have to play around with it to get good picture quality on all channels.

Personally I've never played with a super home node let alone held one, ideally that's what it is made for... if you used one of them you would use a two-way splitter as a combiner to connect the 622's into the node.

Thanks. I think I have it figured out. I diagrammed it in the attached pdf. This is assuming I don't get a Dish Pro Plus capable switch/lnb and need two lines to each receiver. Though since I'll have 5 tuners, I'm not sure how the setup will change.
I can do this either way, but I diagrammed using one sat input each, one to back feed the tuner 2 modulator, and the other to push out the combined signal to the receivers ANT/CATV in.

The super home node will take the antenna and the combined modulator outputs from the dish receivers and combine those together at the outputs. I'll likely need to add a band pass filter on the Antenna side to clean up the signal for the modulator inputs to fit. But otherwise the diagram should work.

Nice diagram... that should work fine. Personally I think you'll have better luck not running DPP equipment, running two sat lines to each of the 622... a lot less combining (signal loss). I'd stick with your diagram.

Only one way to find out.

Don't know how far all of your equipment is going to be from one another, but you might want to think about adding the antenna port into the equation and centrally locate the antenna somewhere in the house, combine them all on the same line... get a few UHF remotes and your set.

When it's all said and done, I would love to see the face on a new guy coming in to do an upgrade.

thanks... looks like with the new 722k, I might need to have a couple antenna lines going to it if I try to get one of those.

The antenna I'm building myself (from this thread How to build a UHF antenna... - AVS Forum) and it will go in the attic space. Then a line from the antenna down through the main floor to the basement where it will connect to the super home node thing. There it will be distributed out to everything. I didn't include runs to the not directly attached DVR equipment but that will be just through a single cable run split off of the #4 port on the home node thing.

Eventually the 501 will go away, but I'll keep using it as long as it works since I own it and it doesn't have a DVR fee.
