TV2 Distribution Question

[kylarse]

I have two dual tuner receivers, a 722, and a 322.

I'd like to distribute the TV2 output of these, to other TV's in my house, over a single coax distribution system.

Can I, Set my 722, TV2 output to channel 73, and my 322 output to 83, and combine these to a single coax cable, and then split this to multiple locations with a standard coax splitter (1 to 6, etc.)?

Thanks for the help, and what do I need to do this. I expect I'll have to take the UHF output from the diplexers in my basement, and combine them somehow. I have a 1x6 splitter, but only the signal I input to the IN comes out clean, any signal I input to an OUT, is degraded, but both 73 and 83 outputs are visible on multiple TV's in my house. I'd obviously like to do this without sacrificing qualition on one of my systems.

I have something similar setup (using a 622 and a modulator on a 510), and I just used a 1x2 splitter to allow both of the receiver outputs to be sent as an input to the 1x6 splitter, and it seems to work fine. In my case I didn't use diplexors since I had an extra coax available to carry the outputs back to my distribution point.

You can also distribute the TV1 modulated signals as well!

I have basic cable for local channels and mixed my 722's channel 73 output with the cable so I can watch any cable channel or dish on SD TVs throughout the house. I used a splitter to combine the cable and 722 lines, then run the output to a Radio Shack powered distribution amp with four outputs. I can even view the QAM digital channels in HD with this lash up.

You can have the output 2 channels apart, that is one blank between, adjacent will cause interference often because they are not stable enough nor band-stopped well enough. Likewise, they should be 2 channels from each other or any cable or OTA, depending on which you add on. There are gaps between 4 and 5 (2 MHz only) and 6 and 7 and 13 and 14 OTA. Channel gap 6-7 is filled with cable channels (14-22) or partially by FM for OTA. All as I remember.

Is there any easy way to block certain frequencies coming in from cable? All the combos of distribution channels I'd tried from my 622 conflict with something that's coming in from Comcast so there's no way for me for combine TV1/TV2 with the cable signal.

You would need a notch or bandpass filter. A good one is not that cheap and would have to cover say 30MHz or 5 channels of 6MHz each or a little less to avoid cutting the pass channels.
cable..margin..tv1..skip..tv2..margin..cable
You would notch the cable signal and add in the recorder signals with a cheap diplexer. The UHF band has channels in steps divisible by 6MHz. The exact frequencies would depend on what was pre-made because a special order would be much more. They may be pre-made for blocking say 3 channels and you would need 2 then. Inquire at a TV specialist.

On some cable system channels 60 to 70 or 70 to 80 are good candidates.

It's a lot easier to use 2 cables and select on the TV if it has 2 coax inputs.

This is how i set mine up

http://tech.dishnetwork.com/departmental_content/TechPortal/images/pdf/tech/DistributionExample6.pdf and how dish says to set it up.

note: This was originally drawn for the 942 which only modulated TV 2 but since the 622 & 722 Modulate both TV1 & TV2 you can do this and get all 4 tuners on the other tv's.
