    So I keep getting put off by DirecTV. Its unbelievable, I don't know how anyone in my area can put up with this. Today's story was they didn't have the LNB for the dish they need to install. It is "back ordered nation-wide" and I have to reschedule. They tell me this over the phone from the call-center...

    So I make a few quick calls, buy my own AT-9 5 lnb dish for $50 and am trying to do the install myself. (Now they won't come out to the house because they don't have the SWM, which I don't even NEED since two wires are already run to my receiver...)

    First of many questions is... I have four outputs on the LNBs from left to right as your looking at it, and four inputs two labeled 13V and two labeled 18V. Which goes where?

    It doesn't make a difference where the wires attach to the multiswitch (of course they need to go to the inputs...) This only matters when using multiple switches in parallel. As long as the four dish outputs go to the four switch inputs you're good to go!

    Thank you for the quick response! My receiver is telling me to set the dish to 207 Azimuth, 52 Elevation and 67 Tilt. Is this correct??

    The receiver bases the info on your zipcode. Make sure the zipcode is correct, and if so, those will be a good starting point.

    Thanks! I figured something like that and went through the receivers menus. Sure enough the settings are completely different (California now vs. Mississippi before!). Looks like its calling for 134/44/114. The dish I bought here locally is already set at 47elev/112tilt. Is it likely this is even more accurate since I assume someone dialed this in previously for approximately this local area?

    I get that a tech should do this with a signal meter. I still intend on making DirecTV show up to the house, run another line, and align this dish themselves. I just want to rough in something that gets me TV today...!!

    The alignment parameters you find in the receiver are generally based on a central aiming point from the center of the zip code. So the dish you bought most likely is aimed specifically for the person who used it last. Make sure the mast is plumb and the skew/tilt set.

    Also, you can use the four outputs without the multiswitch if you only have 4 tuners or less. If you have more, then connect the four lines from the dish to the 4 inputs on thw Zinwell WB68 multiswitch (order doesn't matter).

    I've got the dish connected to the Zinwell (I don't exactly know which outputs from the multiswitch go to my receiver). When "verifying configuration" the receiver says the satellite signal could not be detected...

    I've got the four outputs connected to the four inputs on the Zinwell, the only other thought I could have... is the zinwell suppose to be powered? There is a green bare wire hanging out here that is coming out of the house, I assume that is a ground for the dish? I havn't connected it.

    And when I go to signal strength I get 0's across the board. I have the bband converters installed...

    To be fair I just grabbed a AT-9 that the shop had and an oval dish that "looked right.."! I hope I didn't screw that away and get the wrong dish/lnb combo but I can't imagine how...

    Try connecting a receiver directly to two outputs from the dish.

    I tried removing the multiswitch and connecting directly to the two cables running from the dish to the receiver and am still getting the same message.

    "A satellite signal could not be detected. Please check your installation and re-test."

    Could the satellite being out of alignment cause this? I just took cables from the 4 LNB output and connected them directly to the receiver... I find it hard to believe it doesn't matter what I hook up..

    You dish needs to be realigned.

    Ok, I've got signal on 110deg so we're in business (it still says no signal on Tuner 2, but I'm ready to start tweaking the one good tuner!). Now I just need a quikc hows it done on what satellites I need to be picking up...

    Hard to say, but regardless.

    If you have HD, you need the 101,99, and 103. I'm too drunk and lazy too look up if your locals come off the 110/119 but that will determine if you even need those birds.

    Make sure the mast is level and keep tweaking. The fine tuning knobs will be your best bet once the 101 is dialed in.

    Well... the 101 is dialed in. Averaging low 90's on 101. We have nothing coming in on any of the 103's and averaging mid 80's on the 99c.

    So the 101/103/99 are all in the same ballpark then? I will just keep tweaking until it looks good so long as I'm not targeting the wrong satellite here.. :grin:

    I love to hate directv...:rolleyes:

    EDIT: Well I've got everything except some HD and my locals coming in with just 101 and 99c... I didn't have any luck getting 103 or 119, although I only stayed within the optimizing parameters of 101/99. I don't know if anyone can help me narrow it in any closer than this but this should get me by until DirecTV gets their act together.

    So is there any chance I am missing something here? I feel like I am at a dead end. I've got all my SD, just missing locals and about half the HD programming. I am only getting signal on 101 and 99, but looking at some dbstalk resources it seems the only other satellites I need are 103(HD, localHD) and 119 (localSD). 103/119 are complete zeros so I don't know where to start to try and pickup them...

    I feel like I'm close here, at least we got to watch some TV tonight!

    Please explain this post? An "AT-9" was the first generation of KaKu dishes also known as a "SIDECAR". Are you trying to use a sidecar LNB with an Slimline dish that you bought as separate items? Is your Zinwell a WB68 multiswitch or other Zinwell switch?:)

    Good catch boba, I overlooked that he said AT-9.

    In any case, the OP should make sure the skew is correct for that dish. Then he might be able to very slightly adjust elevation to see if it might hit 103. Of course, 99 might go down, but it at least will show he's in the ballpark.

    I think it may have said its an AU-9... not really sure. I know that it is the correct 5 lnb set for the newer style oval dish, I realized last night that the AT-9 was wrong and for the sidecar. My mistake.

    Its late but I will get up there and check which switch it is tomorrow. I'm pretty sure its a pretty standard and common Zinwell 6x8 that I saw in videos/forum/pics but easiest for me to just check the number.

    The skew is set at 114 already, and that happens to also be what the receiver is calling for per my zip code.

    For whatever reason I only have two turn dials (the ones with the number dials that are socket driver), one for elevation and the other I think for azimuth (?). Perhaps there is an adjustment device missing for the third axis? Regardless I was really only tuning azimuth roughly with the mast loose and then elevation with the turn dial. The other turn dial (azimuth?) appears to be broken as the head of the bolt turns but the shaft doesn't move...

    Sigh, sorry I'm not more resourceful today/tonight but another day of wrestling with DirecTV has left me exhausted. This time we've rescheduled the install for next Wednesday..

    There are only two dithering adjustments, azimuth and elevation. The tilt or skew does not need the fine tuning.

    Let's check and see exactly what you are getting. On 101, you should be getting good signals on almost all of the 32 transponders (a few might be zero, none should be NA). Please list what you are getting in the format shown on a receiver, for example:
    1-8: 92 89 87 90 88 89 91 90
    9-16: 93 93 90 100 88 92 90 90
    etc.

    Then do the same for what you are seeing on 99 (and indicate which 99 (c or s). You will have some NA indications for 99, 103 and 119.

    Did you get your dish and LNB assembly together, or did you pick up a dish reflector one place and an LNB somewhere else and add it to the dish?

    If you are getting one of the 99 satellites and the 101, but are not getting 103 or 119, then there are several possibilities that could cause that:
    1. Alignment is off
    2. Dish reflector is bent or warped.
    3. LNB assembly is defective
    4. Multiswitch is defective
    5. Receiver is defective
    6. Possibly a defect in coax or a connector someplace.
    7. Incorrect dish/LNB specification in setup.
    8. Defective BBC.
    9. Incorrect installation (e.g., splitting a coax line to two receivers in a non-SWM system).

    To address some of the questions you had...

    I got the dish and lnb from the same DirecTV retailer, however the LNB was sitting on a shelf, the dish was outside in the back of the store. So no telling if they really go together. In fact, I must admit I havn't even bolted the lnb to the arm, just slid it in place.

    The switch is a Zinwell WB-68 but has been isolated from the system. I have connected the receiver directly to two (selected at random) outputs from the lnb. I thought the zinwell might be the problem but isolated it made no difference. I got the signal to work only by checking all the connections after isolating the multiswitch. Nevertheless I have yet to reconnect it to the system.

    The receiver is an HR21, I've tried two different sets of BBC converters so I doubt all four are bad.

    There are no splits, again receiver directly connected.

    I would not doubt for a minute that some part of this dish is defective. Although by far the most questionable part of this job has been the dish alignment. Again only one of the fine tune screws is working (elevation). That was like crack for my signal, a few turns and a roommate on the cell phone optimized 101 like butter! However, I have never seen any signal on the 103 and can't fine tune azimuth...

    Here's the receiver readings.

    101:
    96 97 95 95 95 99 95 98
