When you replace the gears in your antenna be extremely cautious because the
base is cast alum. It has a small rod in the front that you have to take out
if you have to replace the antenna portion. The holes in the base that this rod
goes into will break really easy. The base cost new about 40.00. Keep the
gears greased each year and they will last longer. The sun is really hard on the
plastic. jauman
