The Capacitance Hat is designed to help in two ways. First, you can use the capacitance hat with a whip as short as 30" and get the same frequency coverage as the 6' whip without sacrificing performance. Second, you can add the 6' whip to the top of the capacitance hat and get a big improvement in performance on the lower bands. The base of the capacitance hat is 12" tall with standard 3/8 x 24 thread at both ends. It uses 8 stainless steel rods 12" long each at 90 degrees to the antenna for maximum capacitance with less weight
