    Hello,

    I have an HR20-700. When I run the System Test, it shows good signal percentages on both satellite tuners and on Off Air tuner 2, but 0% on Off Air tuner 1. I talked to Directv tech support. They had no idea and suggested I post here. Does anyone have any ideas? There is only one off air in connection on this box so it would have to be split internally to supply two tuners. Since one works and I get all of my local channels, I'm guessing that either Directv only enables one tuner, or there is a problem with my box.

    Thanks

    "Design defect?" Are you serious? If that were the case then nobody would be getting the channels.
    Now you may have an install problem or a defective unit, but from the little you've posted, it's hard to have any idea of what your problems is related to.

    Try telling that to the thousands of companies out there that have been held liable for design defects in their products that didn't affect every single person who bought that product. I can just hear GM telling the jury in a rollover case involving one of their SUVs "there can't be design defect, since not all SUVs have rolled over."

    Well if you can get your HR-20 to roll over I'll agree with you.

    Seriously though: there are manufacturing defects and some poor installs that most of the issues are from.

    Greetings all,

    I have a newly installed HR-20 with the attendant BBC's. I was not getting any of the new channels on D*, so I played CSR Roulette. The first girl said I had to do all the normal reboot, reset, re-setup stuff with her. I did. Then she said it sounded like bad BBC's, so she sent me some more. I replaced my BBC's and messed with the cables. After a few minutes of cable swapping, I determined that the new channels work when I had the BBC's without any connection to my OTA connection via diplexer. When I remove the BBC for the line sharing the OTA via diplexer, I get my locals beautifully, but obviously get the 771 and searching for SAT IN. When the BBC's are installed, I get the 771 and searching for ANT IN signal. The end result is either no new channles or no HD locals via OTA. Is BOTH too much to ask for?

    Just connect OTA antenna directly to off-air antenna input on the back of your HR20, nothing in between. Just hook up the two cables from the AT-9/Slimline dish to the back of satellite in 1 & 2 (Okay to have Zinwell) and you should be back in business.

    Return the setup the way it was when the installer came, any changes you made (adding diplexer) reverse those changes.

    Good luck.

    This HR-20 is in my bonus room. There are only TWO RG-6 cables going to the room and I am not keen on telling my wife that I need to drill a hole in the wall of our house to run an additional cable. The HR-10 we used to have there worked like a champ, and it still does downstairs in the living room. I tried the foloowing:

    WALL -> Cable -> BBC -> diplexer -> HR-20

    and

    Wall -> Cable -> dipexer -> BBC's -> HR-20.

    Both configurations give me problems. BTW: The installer put the diplexers in!

    then connect the OTA antenna directly to the back of the STB where it says off air antenna input.

    Why are you drilling holes, when you can have an installer do it for free?

    Make sure if you insist on DIY that you use RG6 that is rated for 2300 MHz or 3000 MHz. It will say on the wire what the rating is.

    Okay, let me break this down for you:

    I have it connected correctly...you know why? Because I am an Electronics Technician in the Navy...I work on the electronics for a nuclear propulsion plant. I understand electronics quite well. That is not the problem.

    Hole: Because other than a diplexer, I know of no other way to run three cable signals over TWO cables going to the room.

    What I do not understand is how the diplexer I have, which is rated correctly for the frequencies in use and the BBC somehow make the signal get lost to the AOT IN copnnection when the BBC is in parallel, not in series with the signal. The only thing that makwes sense would be if the BBC's load down the circuit such that there is not enough signal strength to pass to the OTA in. I have an amp that I am not using and I am considering using it, but only as a last resort.

    Now I didn't work on nuclear propulsion, but I did work on electronic warfare systems for nuclear strike aircraft. [yeah, I know... big deal :lol: ].
    What you've described sound like a bad diplexer [or one that is directional and used backwards].
    The BBC up converts 250-750 MHz above your OTA 54-8189 MHz, yet you don't seem to have the isolation between the two ports on the diplexer.
