    Hi!
    I recently switched to DirecTV from D*Net.
    The HR20 requires 2 coax inputs (D* had a diplexer of sorts merging 2 coax into one input)
    Can anyone tell me when DirecTV will have this technology available to allow
    me to route my ATSC signal through the HR20?
    Only have 2 coax outlets per room.

    Thanks for your help!

    I think you mean E* (DISH Network) instead of D*(Directv). Sometime this fall D* should have the SWiM available (single wire module).

    That will combine the 2 sat runs but you still need to run your OTA signal in a separate run to feed the OTA input on the HR20 right?

    It would "preferred" that you keep it seperate.
    But the SWM shoud allow you to diplex in your singal for OTA

    The SWM will allow diplexing of the OTA signal along with the 2 sat feeds on a single coaxial cable. You will still need to diplex the OTA signal out to the separate OTA port once the cable gets to the rear of your HR20 though.

    Edit: Earl beats me yet again

    I have my OTA diplexed from one of the sat cables today and it works fine. DTV installers couldn't do it so I called an independent dealer (DISH provider) and they did it for me.

    When the ka low band becomes active later this year, that will no longer work. :(

    It is also important to note Earl's "preference" to keep it separate. There is loss through the dixplexing (certainly on the OTA side), and it may present a problem for some of the OTA signals, given the picky nature of the OTA tuner in the HR20.

    If at all possible, a separate run for OTA is preferable. There is no free lunch.

    As you know...there is a loss through anything added into the system, [SAT & OTA] since no "lunches are free". :)

    Except that, when released to the general public, who mostly have only one cable running to their equipment, it will have to be diplexed. Right?

    I'm part of the general public and have had a separate cable for OTA for my entire life. Actually, anyone with an HR20 (already) typically has two lines. They could go SWM for the HR20 sat and use the spare for OTA, if they like.

    The important point here is that diplexing while convenient, is a compromise that one may not be happy with. I can see a whole slew of new problems coming up from this. I wish they had never offered diplexing as an option.

    One would be wise, during the initial installation to run a separate line for OTA-HD, if OTA-HD is going to be important. If OTA is worth doing, it's worth doing right.

    To add: if you need to use a mast mounted pre-amp, diplexing will be harder as the power inserter will need to be "up stream".
    My installer was quick to say he could diplex my OTA with my dish, without any knowledge of the Ka Lo signals or my pre-amp.

    I'm not certain that most of us in these forums can really be called the "general public" when it comes to using this equipment. :) Isn't the SWM designed to gain subscriber's from those that have cable today and don't have that extra line for OTA? If yes, than diplexing was integral to the design of the product and, while a compromise, needs to work as well as possible.

    In my case, I lost enough signal with diplexing that I added an inexpensive UHF amplifier to see if I could easily boost the signal. It worked, but, IMO, the signal still needs to be improved prior to wide distribution of the SWM.

    My addition of the amplifier certainly shows that you are correct, AND that D* needs to improve the way the OTA signal is handled so that the impact of diplexing is minimized.
