    Greetings and thanks for accepting me. I moved my dish to a better location. I have now decided there is a limb on a tree blocking my HD from 103. Highest I can get on it is 50%. I get the 101 in fine in the 90% range and am getting my Locals in HD and a few like TCM. NG and TlC in HD too. I get all my channels in SD fine. I did pay a pro to come and he did no better on signal strengths but did suspect a limb was the culprit. 20210426_195537.jpg 20210426_195547.jpg 20210426_195601.jpg There are three trees in the general area and I would love to know which one it is. The land is not owned by me though the owner will cut 1 down for me. I am using Satellite Pointer app on my LG phone to try to decide which one. I also have read about the ins and outs of such apps like giving the app several minutes to lock on GPS Satellites. Any suggestions would be helpful. I have a couple more questions too. Thanks for any and all help

    We need to see the dish in the photo (preferably along the under side of the arm). From what little I can see, I'm thinking your problem isn't the trees but rather the LNB being iffy.

    The LNB is offset relative to the center of the dish so the signal is actually coming in at an angle that is double that offset higher up.

    There are device apps that can help you visualize where the satellites are.

    The site www.dishpointer.com will give you aerial view that may allow you to figure out which tree it might be (if it is indeed a tree). Place the tip of the pin (a small crosshair will appear as you hold the pin) right where your dish is and tell it you're shooting for 103W. The web app will draw a chartreuse line from the satellite location to the the tip of the pin. The line will cross any possible obstructions.

    If the problem is a tree and because the satellites are only a few degrees apart, chances are the other slots will soon impacted as the trees grow (or possibly as soon as the leaves appear this year).

    What state are you in? How far north? None of those trees in the distance appear to be at fault, but that pine branch that looks like its hanging right over the top of the dish looks suspect.

    Now that I look again, I think I see the end of the dish arm tube in the first picture (showing the ground wire attached to the lower mast clamp bolt?).

    It would seem that the arm is pointing significantly above the treetops. I'm thinking the LOS is well above a line through the tube.

    Thanks for responding to my plight!! I have installed several SD Dishs back in the day so I am familiar with installing them. I was very confident I was well above those trees too. But I don't understand how the signal comes down and interacts w the dish. I was having issues w this LNB I suspect before. I had to unplug the SWIM power supply several times and the channels I was missing came back. I will get a couple better pictures of the LNB arm tonight.

    Another shot. I did order a new LNB from Amazon. Only $16 and one I have is at least 9 years old. DSC03026.JPG

    Nothing is in the way in the distance. It has to be either the tree above the dish, or the electronics. Also, at 9 yrs old, its possible the squirrels got to the coax too. If you play pool, the dish is the same idea. Go straight out of the LNB eye, hit the dish at an angle, and bounce off the opposite direction. For Ohio, the angle to the satellite from your dish surface is about 35 degrees above the horizon.

    Maybe a "new" Dish wouldn't be a bad idea either.

    There are numerous apps for your phone that fairly accurately locate the satellites.

    I've new coax except for a few feet from inside to the outside of the house. I'm sure glad I didn't have any trees cut down! I did trim a lot of limbs I thought were possibly in the way on the tree behind the dish. I put a new picture up.

    Can I get by replacing just the dish and L N B arm?

    No reason you can't --You did order a New LNB already do that should be good to go --If you have a Very long RG6 --Lay it out on top of the ground and see if that changes anything

    You can easily replace the LNB.

    If the problem is with the arm itself, you should replace the whole dish as arm damage usually causes dish deformation..

    Onside ring you can get an entire new dish for 100 or less, I’d replace it all.

    Had a dish that had an issue once and you couldn’t even see the problem. New dish solved it immediately.

    Also make sure you are plumb on the pole…. SD dishes are far more forgiving than Hi Definition. You really have to tweak it right for Hi Definition. There’s plenty of info on fine dithering to get a good Hi Definition signal

    So the three lines are the three different Satellite signals?? And what is the order of the satellites shoown top to bottom? Thanks a lot. This gives me a very good idea of how a multi Sat dish works.

    I guess I will go pc by pc, LNB first then Dish and aiming mechanism. I had a new complete dish sent to me from Amazon but the dish was damaged. Could not get a thing so I sent it back. I am very plumb w the pole. IMG_20210403_114550.jpg
