The tree is changing the velocity factor of the element in your A99 and making it look "longer".
You have 3 choices-
1. Remove the A99 from the tree.
2. Install the A99 so it is way above the tallest part of the tree with no tree anywhere near it.
3. Cut the antenna (shorten it).

tech 833 is right. id opt for choice #1
cause choice # 3 if ya move or tree falls
your asntenna will be pretty much junk.
