That's a good point on canopy(limbs only are canopy): it will not penetrate it. And when you do get data, it is corrupted by multipath. As far as antennas, if you don't have a external choke ring, you are not going to know the ground truth/correction postion with which to compare anyway. If you are within 10 meters you are doing excellent. Always hold the device as high as possible before saving a set of coordinates to get the best possible horizon.
