    I finally completed the upgrade described in my post #171 of this thread, and we now have another confirmed good solution. My original setup used an 18" round dish for the 101 satellite and a Phase III 3-lnb oval dish for 110 and 119. These were combined by running the 2 wires from the 101 to the no-tone inputs and 2 wires from the 3-lnb dish to the 22 kHz tone inputs of a 4x8 multiswitch. I replaced the round dish with a WNC AT9 dish with the side arm containing the 110 & 119 LNBs removed. Two of the 4 AT9 outputs go to the leftmost inputs of a Sonora HRPID 1422 polarity locker and power inserter, and the other two each go to one of the Holland HFS-2P splitters used as combiners. The two wires from my old 3-lnb dish go to the other side of the combiners, and the combined satellite signals (coming from the jacks marked IN on the splitters) go to the remaining satellite inputs on the Sonora. The four outputs of the Sonora go to the four inputs of a Zinwell WB68 multiswitch, as shown in the previous drawing, and the outputs of the multiswitch connect to the satellite receivers.

    Signal strengths on the 103b transponders range from 93-97, and on the 110 and 119 are pretty much unchanged from my previous levels, so I don't think the combiners and power inserter are causing much, if any, degradation of signal strength. I seem to be getting all of the new HD channels successfully, as well as the old HD channels on 110 and 119. Thank you to doctor j and litzdog911 for blazing the trail.

    I'm left with a brand new CalAmp AT9 dish which I bought in case I had to resort to "Plan B", but fortunately that wasn't necessary.

    I have a Phase 3 dish that is not being used and is free for anybody that is in a situation needing multiple dish setup.

    A family friend upgraded to the AU9 and the installers left his Phase 3 in the garage, he gave it to my sister who right after they replaced their original dish with the phase 3, upgraded to the AU9 as well.

    Just cover the shipping and the dish is yours.

    I love reading about these interesting setups and ways people get around limitations of their areas to get a service they want.

    Very impressed by everyone in this thread.

    I don't believe a Phase III dish will work since it has a combo LNB/multiswitch The Phase II dish has separate LNBs and separate MS mounted on the back of the dish. Thanks for the offer.

    Actually I believe the phase III will work. The multi-switch in it isn't an issue.
    If the LOS is very narrow, then two separate dishes may be needed, located so they both can get LOS.

    Maybe I stated that badly as I'm fairly new to D*, the dish has 3 lnbs on it.

    But from the reading and research I've done, I'm pretty sure its a phase 3

    Take a look at the pictures here and you should be able to tell.

    VOS: Won't the 101 signal from the Phase III LNB cause a conflict when couple with the 101 signal from the AT9 LNB? Two signals from the same sat - not good.

    It's phase III

    101 is the "no tone" while 110 & 119 are the "tone", so why would the Phase III even connect to the 101 LNB?

    Maybe so. But I learned long ago, one test is worth a thousand opinions. ;) Care to give it a try?

    The polarity locker ensures the LNB for the 101 satellite is never selected on the Phase III dish. The two wires from that dish always receive the 22kHz tone. and the signals from the 110 and 119 satellites are combined with the signals from the 103 satellite through the two wideband splitters used as combiners.

    The results of "giving it a try" were reported in my post #201 with a photo of the actual installation. The diagram showing the required connections was in my post #171.

    I learned long ago to know how something works before making changes.
    1) the problem you elude to is with the 5 LNB and having the 110 & 119 still powered. The control signals used for them also control the 103 LNB. Since this are needed, if you don't have an AT-9, where you can disconnect the 110 & 119 LNBs, you will have problems using the AU9.
    2) So if you are using the AT-9 99/101/103 LNB, you can combine the phase III to the 13 volt 22 kHz & the 18 volt 22 kHz lines and have: only one LNB active for: 99, 101, 103, 110, 119, which is what is required.

    Anybody see a flaw in this logic? Please post it. :)

    Ah, thanks. Somehow I missed #171. So it looks like we currently have 3 working methods. Now if someone could figure a way to use a AU9 instead of AT9. I see someone posted dissected photos of the AU9 LNB.

    When post 171 was written, it was a proposed methodology. After trying it and determining that it worked, jbraden wrote post 201 and updated the diagram in post 171 to show that the, previously proposed methodology, is now confirmed to work.

    As a final follow-up to my 2-dish solution, I emailed DirecTV and explained that because of my line-of-sight problems, I needed to do a custom install in order to get access to all 5 satellites, and itemized my expenses. I requested programming credits to help compensate me for the materials and labor involved, since DirecTV did not have to pay for a dish and install directly. DirecTV called me back and offered credits of $19.99/mo. for 12 months, or $239.88 over the next year. Although this doesn't cover all of my costs, I thought it was a very fair offer, and I certainly am going to enjoy the new HD channels over the years ahead.

    To take jbraden's comments one step further, I would suggest making this phone call before spending money to get the multi-dish solution implemented. At that point you have more leverage with DirecTV.

    My original upgrade offer from D* was a free upgrade of my HD DVR, HD receiver and installation of a Slimline. They would then upgrade my HD reciever to an HD DVR for $199. After it turned out that this wouldn't work and the installer cancelled the installation without even going on the roof (and then the supervisor, who was supposed to come out to do a site inspection, never showed up), I was in the process aquiring an AT9, I called D* because I was concerned about the fact that I would be getting the AT9 installed without a current generation HD receiver available for alignment purposes and didn't want to get hit with a new 2 year commitment in case the multi-dish solution didn't work for me.

    I spoke with a Customer Retention person, who understood my dilemna. She told me that they couldn't waive the two year commitment, but that she could send me an HD receiver for free, which I shouldn't activate until after we use it to align the dish and are happy with the results (which, unless I get rained out for the third time, will occur tomorrow).

    Then I need to call back for the two HD DVR's, which will now both be for free.

    Like jbraden, they didn't completely cover my costs. However, given all of the other things that they were already giving me for free, I didn't expect them to.
