Abstract

An antenna system (10) is disclosed that includes a base section to which a signal connector may be attached, and a radiating section (20) distal form said base section. The radiating section (20) includes a flexible electrically conductive material and an adjustment system (26) for changing a length of the electrically conductive material responsive to a control signal.
