    I have a DISH installed from the fence at my house, I'm still tuned to channel 998 from the 129 satellite on my Hopper 3, checked the signal strengths, but currently having weaker strengths. Hope that some guys might have the same issue as I am.

    Anything on 129 transponder 1-16 are on spotbeams - the only ones that should have decent strength will have your locals on them.
    17-32 are CONUS transponders - they have national cable -type channels on them. They should be a minimum of 40 (usually more like 50+). SO based on what you posted - you have an aiming problem. 119 and 110 usually have better signal strength than 129. In any event - call Dish for a tech visit to repoint your dish.

    Your 110 and 119 satellites don't look so good either.

    What does "from the fence" mean? Perhaps a photo would help.

    Your numbers are poor across the board. They should be at least 30 points higher.

    Can we see a picture of the dish on a fence?

    I will post my picture in a meantime. It's getting pretty windy to me.

    Windy and a dish mounted on a fence? Sounds like a personal problem. :)

    I wouldn't worried about you :) your camera is making a picture for 1/100 sec, so no worry !

    Unless you're talking winds of 20MPH or better - that's not really an excuse... just saying...

    Has that fence post shifted since it was installed ?

    I still think you need a repoint, because ALL your numbers need to come up.

    nay, I would use a pipe in a concrete slab, not the wooden post ...

    There's a correct install in the left side of the second photo.

    Wood posts have never been recommended for pole mounts and this one has the distinction of having a array of sails affixed to it.

    Currently aiming at 129, and I think it was blocked by trees, or the fence loosening. Some main HD channels from 129 redirects to the SD versions from 110 and 119.

    The numbers you're getting suggest that the problem is aiming, not line-of-sight. They're in about the right proportion, just a lot lower than they need to be.

    Strangely, that one is not used for new dish... btw it has no LNBFs , so I wouldn't name it as "correct" install :) !

    I'm betting the old setup was blocked by the building.

    I wouldn't bet on that without real knowledge.
    And odds are against you - that dish is the same HD, eg with 3 sats reception.

    You're probably right. I had a deuce of a time dialing in 129. OTOH I've also had to move a dish due to a tree getting a little bigger.
    For the OP, you said "currently" -- does that mean the numbers were okay before? Did the problem start when the tree leafed out this spring? Do the numbers jump around when the wind blows? (yes, I know that could be the dish moving on an unstable mount, but tree branches move in the wind as well.)

    One needs to start with better information. Use a cell phone app like "Satellite Finder Pro" (not an endorsement - I found the app hard to use and it has too many ads). Use the "AR" mode (augmented reality) on whichever app you use so you can aim the phone at the sky and see the satellite arc superimposed on the screen. Then you will have an idea of where the satellite arc is and what trees or buildings may be close or obstructing.

    Here is a sample screen shot.
    SatelliteFinderPro.png

    If your fence post is not concreted in place it probably has shifted. It is possible for even a concreted post to shift. Lag bolts can come loose and dishes can be bumped. The fact that you can still receive some signal is hopeful. you just need to figure out how to readjust your dish without making the situation worse. Low signals on the meters don't tell you which direction to turn the dish or how much the foot holding up the dish has sagged (if it has sagged at all).

    The install directions for the dish is to start with a 100% level top on the mounting pole. Imagine the mount without the dish ... just the foot and the angled pipe going up to the dish. You should be able to put a level across the top of that pipe in any direction and be 100% on the bubble. Any deviation makes the next steps harder. The weight of the dish and cabling can change the leveling of the top of the pipe when connected to a foot as shown. Unless everything is 100% locked down weight over time will cause the dish to tilt away from vertical. This is in addition to any shifting of the fence post.

    The next step is to set the skew on the dish and never touch it again. The skew will line the dish to make the satellite arc be close to a straight line across the middle of the dish's view. Note that it is still an arc. When you are aiming at three satellite locations the center one (119 in this case) will be higher than the others. (110 and 119 should be at the same level.) This is a set and ignore because it gets too complicated to adjust three different settings when dialing in the dish for best signal.

    The third step (1 - level mount, 2 - set skew) is to set the elevation on the dish ... what angle off of the horizon will the dish be looking? This is the easiest thing to get wrong when guessing where a dish will aim. It isn't hard to find the right direction on a compass, but most people have problems with height above horizon. That is why we have aiming charts and websites. :) Set the elevation but be prepared to adjust it. The fourth step is to point the dish at the right azimuth, which for a Western Arc DISH dish will center the dish on 119. If all has gone well you should be able to see all three locations with some signal level.

    The final fine tuning can be a challenge and is ALWAYS a compromise. Getting the dish exactly tuned on 119 (azimuth and elevation) puts both 110 and 129 outside of the exact center of their LNBs. But that is OK. Ku DBS is designed with this level of error in mind. LNBs spaced to work in Seattle or San Diego are designed to pick up more than the exact center of where they are aimed.

    Here is the screen shot above modified to show the three western arc satellites with a horizontal line between 110 and 129 and a vertical line down from 119 for reference. The app will show the azimuth and elevation for the circle in the center of the screen.
    WesternArcAim.png


    In your situation start with marking the exact location of all parts so you can go back to where you started. After verifying that the top of the mounting arm is level I would carefully and slowly turn the dish clockwise as little as possible until the signal improves. If the signal got worse go back to start and turn counter-clockwise as little as possible until the signal improves. When you hit the point where the signal starts to go back down STOP. Check all three satellite locations and lock it down.

    Did you get Dish tech out there for the repoint yet ?
