Abstract
A tunable antenna system includes an antenna, a tuning mechanism, and a key that relates points of adjustment in the tuning mechanism to different installations of the antenna. The antenna can be tuned for a given installation by applying the key to the antenna without specialized knowledge or equipment. The system also includes a set of tunable antennas, each being tunable within a different range of electrical lengths. The number of antennas in the set is sufficient to cover a total range of electrical lengths for a given set of installations. Fewer antennas are needed to provide a tuned antenna for each installation.
