    Ok. So while my signal levels are good, and I dont really have any rain issues unless it is bad thunderstorms.. I still think something is off regardless of the amount of tweaking

    So after ruling out the tree, I am wondering if the dent on the dish could cause an issue or if possibly i am mounted to close to my house.

    Current Signal levels- Clear outside, humid, dish is a little wet(alot of rain last night)

    These levels are slightly lower than when measured last in the winter

    I have attached pictures of the dish, and location. you can also see the one tree in question. But i did check again with Norsat yesterday and the Sats sit well above the tree. I may be over thinking and this is the best i can get for my location but who knows.. I have a SWM-16 with all new SCC cable to the dish. Distance from dish to SWM is about 90FT

    The SATS go from right to left in the picture. so in 6, 103 is to the right

    Those are all good readings, and if you are not having any symptoms or problems, I wouldn't worry about it.

    while 103 ca & cb can be tweak just a bit, perhaps half a turn, I agree with carl, nothing to worry about

    Could it be reflections that account for his slightly lower signals, if indeed he's tweaked it as best he could?

    After all, satellite signals reflect off metal, and he's got metal right next to that dish, and there are other Ka birds in the sky.

    The downspout and whatever other metal may be nearby. If its just the gutter it might not be enough, but there may be a lot of metal under the siding at that corner, depending on how it is framed.

    I was posing this question more to people who would know like peds48. I have no idea if this can be a real problem aside from aluminum siding, which that doesn't appear to be (unless it is vinyl coated aluminum)

    Don't over-think this. Your readings are fine.

    If you can't stand great readings, you might try tweaking the elevation for a chance at a little bit greater readings. Of course it is just as likely that you do more harm than good.

    No amount of tweaking is going to stop rain fade if your area is prone to heavy rains.

    according second picture he is OK, a reflection from flat surfaces like the guts will not create measurable interference to the reflector

    It's framed with wood , not metal, and the corner is vinyl.
    downspout is the only metal I see.
    Only commercial buildings have metal framing.

    Also , just so you know I have that same dish with the raised edge, and I have a smooth edge dish, and the raised edged dish is 3-5 points lower than the smooth edged version.
    So I would say your peaked.

    What do you mean smooth dish vs raised dish?

    There are 2 slimlines, one that has a raised edge on the reflector around the outside of it, and one that doesn't.
    The 4 mounting bolts are also different measurements, so they can't be swapped out without changing the reflector mount.
    Which requires a complete realignment.

    Later if someone doesn't already post a picture, I'll post one.
