text: how far to the left and right should a satellite be free from obstructions? there's a tree on the left that's about 25-30 feet away and trees about 200 yards that go very high in the sky. could one of the far off trees be weakening my signal? any help and answers are appriciated! well i dont think so trees shud affect ur signals. as we know that these signals can pass through walls and small objects so i dont guess trees shud affect ur signals. might be u check ur satellite position and rotate and see to some other direction. this wud help you.
