    So...I upgraded to the HR20 from my HR10-250 and have run into a problem with my "master plan" to clean up my home theater wiring. While trying to use a combiner/splitter for OTA and Sat feeds, I determined that the combiners/splitters are apparently filtering my high frequency (>50) local OTA frequencies.

    Any thoughts on how to accomplish this setup given the apparent filtering of the high frequencies?

    Thank you!

    If you mean diplexers, if they are the correct ones they should not be filtering out the high frequencies. But it's a moot point anyway, because diplexing will not work once DirecTV10 launches in early July and starts transmitting signals which come from the LNB in the b-band. That frequency band overlaps OTA and so your diplexing will fail. You need to run a separate coax from your OTA antenna, through an OTA splitter or distribution amplifier, with separate OTA cables to your receivers.

    Or wait for SWM [Single Wire Multiswitch] later this year [3Q to 4Q]. There is a thread in the CE forum where some forum members are testing this device...

    http://www.dbstalk.com/showthread.php?t=81489&page=37

    It "may" work out that you will be able to get this device shortly after the new satellite goes operational.

    Cheers,
    John

    Put your BBC converters after your Multi-switch and the diplexers after that.

    Look at this thread: http://www.dbstalk.com/showthread.php?t=88202

    Many thanks for the info. So, let me get this straight...BBC Converters are the same as the b-band converters that came in my HR20 box? If so, is your suggested setup going to work once DTV starts transmitting the new content later this year? Just trying to determine if this is a short-term fix or if it will work in the long-run.

    Also, why would one diplexer work better than another if they are rated for the same frequencies? With that said, is the CM pair compatible with the upcoming transmissions?

    Sorry for the "basic" questions...thank you for your help.

    There is a 99.9% chance that diplexing OTA will stop once D10 starts transmitting. It won't matter where you put the BBCs.

    And that is based upon what information? The B-Band converters move the sat freqs that are being transmitted in the same freq as OTA to freqs that are not where OTA is.

    Diplexers take out gain. The CMs take out less. If it is short-term solution the all you are out is about 20 bucks. The SWM switch will be out shortly after the new satellite begins transmissions. It is provides a means for diplexing OTA "out of the box"

    Any feel for how successful I will be with frequencies in the 50-65 range using the CM pair? These are the ones I was losing with my other diplexers.

    Also, what is the expected cost of the SWM switch?

    Again, thank you!
