A friend of mine installed our antenna on our roof because I don't have an extension ladder and am afraid of heights, but there are some things that still need to be done, such as installing the ground and adequately aiming the antenna as well as maybe installing a rotator. There is also an old Dish Network dish in the same area that needs to be removed and it's possible the cable and ground from that could also be used for the antenna. Is there anyone around San Antonio that can do these things affordably?
