    Ok a thought I just installed another HR21 in the bedroom and it sits on top of a table where it is kind of visible. Can the B-Band Converters be put up in the attic right after the multiswitch and then put the coax going to the bedroom right into the box so I don't have to have them in the bedroom.:rolleyes:

    I believe that will work fine but hopefully someone will have a answer for sure for you.

    BTW I am moving this to the "DIRECTV General Discussion" forum.

    You can, but try to keep them as close to reciever as possible.. Also make sure they are in the same direction as they were (pigtail towards reciever)

    B band converters work best right behind the HR21, but can be put anywhere between the HR21 and the Multiswitch.

    Should work, just give it a try and if it does not work you know the problem ;)

    As houskamp said, just make sure they are still in the proper direction.

    There is no reason whatsoever that the BBCs must be connected first in line at the receiver inputs. I have installed BBCs right after the multiswitch, and everything works just fine. Be aware that when doing this you must maintain the same input/output orientation of the BBC, which requires a short cable with male f-connectors on each end to couple the multiswitch output to the BBC input, and a barrel connector to couple the BBC output to the input of the cable run to the receiver.

    just be aware they have a tendency to fail, make them easy to access.
    I wonder though, do they fail due to being in cabinets and possibly having bends in cable?
    might experiemnt with this to see.

    Why would the BBCs work any more reliably when close to the receiver as opposed to right after the multiswitch?

    That would only be true if there is a significant voltage drop on the cable or the cable had bad connectors, or if they were put in a humid or damp environment. They are not designed for outdoor use.

    I've had 3 fail inside behind the receivers, so keeping them in the house isn't that reliable either :)

    Since the converter translates the frequencies to higher ones, there would be more signal loss in a longer cable, and signal loss is greater at higher frequencies.

    That is probably why it is technically preferable to put the converters at the receiver; to minimize the distance the higher frequency signals must travel.

    However, I have never read of anyone having a problem with remotely-mounted converters.

    That's a legitimate point, although there are more signals of the same frequency range and some with even higher frequencies that the same cable run has to deliver all the way from the dish, so if it can deliver those signals successfully, it should be able to handle the BBC output frequencies.

    Like I said, it seems to be working for everyone.

    Maybe the signals from the converters are not as strong as the signals in the same band coming from the LNB.

    just like diplexing, it's unsupported/not recommended..
