Recently we had a situation similar to yours on Echostar 61.5 satellite. There is a very small opening between the trees to get the signal from the satellite. The trees are very tall and heavy with leaves. We changed the 18" (which does not get the signal at all) to a 36" dish. Even with a bigger dish the signal is weak (about 65-70) but the picture is good most of the time. I might post a picture of what I am talking about in a few days.
Now in your case, changing your dish to a bigger dish (30" or 36" dish) will help a lot. As long as there is a tiny opening between the tree branches for the signal to pass through, the new dish will grab it. Our dishes however are designed for receiving signal from one satellite. So you could use it for 119. I haven't tried it with two LNBFs like the
DISH 500, but it might work. Can't confirm until I try. Maybe next week I will try it and report to the forum.
