    Only after you perform some modifications to the LNB as carl6 mentioned above. It is NOT trivial and requires doing some math on the elevation (probably only once in your case).

    One note about using a SWM LNB, if you are trying to get HD reception:

    Using a "satellite finder from Radio Shack" is tricky, since it will lock only onto the 101 Ku signal. The Ka beam width (which carries the HD signals) is much narrower than the Ku beam. You can have an excellent Ku reading and still have poor Ka. You should watch the YouTube videos on aligning a Ka/Ku dish before attempting it.

    EDIT: Actually, I'm not sure an old style "satellite finder" will work with a SWM LNB at all.

    Yes, this is just fine.

    When you hook this up, be sure to hook up the cable from the dish to the power inserter, cable from power inserter to the receiver, then plug in the power inserter and lastly plug in the power to the receiver.

    Your receiver should automatically set up the right dish and now you just have to aim it correctly.

    well after hours of pulling my hair out im pretty sure its confirmed that my Satillite finder from Radio shack does not detect the HD signal.....i get nothing....
    To confirm, i have my Phase III dish with SL3 SWM LBN....going to a Power Inserter then to my HD receiver.....it doesnt pick up any signal....it it impossible to align them without a satillite finder>? should i buy one online that picks up HD signals?.....so close, but yet so far away :( any thoughts that may help me get this working?

    Portland,...
    You can use your receiver's signal strength screen.

    This is what I would recommend. You can get signal meters that read SWM and from the Ka satellites, but they're expensive. Solid Signal has some if you REALLY want one http://www.solidsignal.com/pview.asp?p=SUPERBUDDY29&d=Applied-Instruments-SuperBuddy-29-Satellite-Signal-Meter-with-21-and-29-Volt-Module-Powers-SWM--WildBlue-%28SUPERBUDDY-29%29 http://www.solidsignal.com/pview.asp?p=AIM&d=AIM-Advanced-Installation-Signal-Meter-for-DIRECTV-Satellite-Dishes-%28AIM%29&sku=610370580820

    This is how I aligned the 3 dishes that I worked with.

    Go to dishpointer.com and type in your address,
    Go to the panel below, scroll way down to multi sat and choose the DirecTV 99, 101 and 103 dish.
    go back up next to your address and click the go button.
    Look at and write down the readings and take a look at the green line. On the right hand side of the page is a check box to check for obstructions. Click on it and see if you have any.

    Set the Skew / Twist on the dish and forget it.

    Set the elevation on the dish. Make sure you are using the right markers on the hardware for this alignment.

    Move the dish in the azimuth / east and west movement about 10 degrees too far to the east from what the dispointer told you to set it for.

    Ditch the meter.

    Have someone look at the signal strengths on the screen for the 101 and relay the reading to you while you slowly rotate the dish to the west.
    When you get a signal move it very slowly and stop each move to let it lock in on the signal.
    When you get that as good as you can. Then adjust the elevation very slightly and go up and down ( do the dither in the video that Titan25 had you watch ).
    Go back to the east and west movement and dither it.
    Now check the 99c and the 103ca. They should be good also.

    Remember, you are aiming at something thousands of miles away.

    Want to emphasize, go slow. It's very easy to go right past the signal point without ever seeing it if you are moving too fast.

    One must keep in mind that the elevation for the Phase III dish must be offset for the Ka/Ku LNB. Failure to do so will lead to unimaginable frustration.

    ????
    The Phase III 3-LNB dish does not have a "Ka/Ku LNB". Aiming coordinates are easily obtained from http://www.dishpointer.com.

    If you look around post #12, the OP was contemplating retrofitting the dish with a SWiM LNB. If that were the case, there would be an offset in the elevation as determined by experimentation and documented in the Phase III Ka/Ku thread.

    yes, i put the SL3 LBN on the Phase III dish.....dish pointer says Elevation 37.8, Azim (Mag) 209.4 and Skew 73.3......now do i have to do calculations to get my Eleveation Offset or does Dish Pointer calculate that for you?

    when i go to the 101 signal strength meter, what trasponder number to i set it to or do i try them all?

    I used the full screen ( all transponders ) .
    You should get several that are 100 or close to it when you are right on it.

    Have this combination for TV in my camper. Never had to "calculate" elevation.

    Set it to the elevation from dishpointer or the reciever and sweep for signal. i do have to fine tune the elevation to get the best signals across all 3 satellites, but can always catch the 101 using the recommended elevation.
