    This is correct.

    We do that with my setup described upthread and have no issues -- but our multiswitch is in the wire closet below the antenna's attic location.

    Ah. Cool then. I did not know. Dad just said he could record two OTA at the same time. I just assumed there were two inputs.

    Thanks!


    **********************

    So wait a minute. If I buy a 4x8 multiswitch (and it has that 5th input for an OTA antenna)... if I hook the OTA antenna to the multiswitch, then take two lines (out of the 8 coming out) and run them to my HDTIVO, do I need to put a diplexer on the end to split out the antenna from the sat line on one? How do I get an antenna feed out of those two lines I just ran to it out of my multiswitch?

    Yes you need a diplexer on one of two lines going to your tivo,creating a third line which would go to the antenna input.

    i think someone asked this earlier, why not just run the cable for the antenna directly into the tivo?

    Because a lot of people ran there cable to a central wire closet, then out from there. And they don't have that extra cable running to all their TV locations.

    And yes, we know that we are screwed if we want MPEG4/AT9 dishes and still keep OTA and 2-tuner capabilities at those locations.

    So a multiswitch doesn't have an input for an OTA antenna? At least the Zinwell I bought (4x8) didn't.. it had a POWER input. WTF is the power for? Will it work without it? So I guess I just hook a diplexer up to one of the 8 outputs, then run that line to the TIVO, and put another diplexer on the other end with one into the sat in and one into the OTA? Does it matter which one goes in where?

    Power is supplier by the receiver for an unpowered switch. A powered switch is a more reliable power source for longer coax runs. A diplexer is marked Sat and Ant in addition to the common leg. The dish coax goes to Sat and the antenna coax goes to Ant at the top. At the receiver end, Sat goes to Sat and Ant to Ant.

    I still have a question regarding this diplexer. I looked at Solid Signals site. The diplexer is:

    http://www.solidsignal.com/prod_display.asp?PROD=SPDX100&xzoom=zoom#xview

    The image however confuses me. I thought I'd put the 'top end' diplexer onto the 'out' from the multi switch run that I wanted to use (with another diplexer at the TV end) for my OTA.

    This pic indicates that the diplexer goes BEFORE the multiswitch. Does that mean I need four of them? Or just one? If one, how do I know which line coming out of the multiswitch (or LINE(S) coming out) that should be split at the TV end?

    Geeze I feel like a dumbsh*t sometimes but I don't really understand. I don't mind trial and error, but I hate to buy more stuff than I need. :)

    That diagram is trying to be generic and cover either case whether a multiswitch is used or not. In your case, just connect the first diplexer on the one line from your multiswitch that you need to use and the other goes near the receiver. In other words, on the left diplexer where it says "Satellite Connection", make that one of the outputs from the multiswitch.

    Bad diagram. Put the diplexer on the line from the multiswitch to the receiver. One way to tell which line is to disconnect all the lines out of the multiswitch and into the receivers. Short the center to shield on the line at the receiver you want to use. Take a multimeter to test the lines at the multiswitch to see which one has continuity or even take a nine volt battery with test leads to see which line causes a little spark when the leads are placed on the center and shield.

    Do I HAVE to use a short jumper of coax to go from the multiswitch to the diplexer? Do they make a female/female connector to screw onto the male connectors of the multiswitch (out) and diplexer (in)?

    I think you would need a male/male connector. A quick search on google turned up hundreds of results. here's one
