ABSTRACT:
An extensible antenna, particularly for automobiles, incorporates a plurality of inter-connectable elements which are separated and wound on separate reels when the antenna is retracted. The antenna elements pass from the reels through a connecting mechanism, such as a plurality of rollers, to be connected together for extension of the antenna. The antenna elements each are formed with a longitudinal groove on one surface and a longitudinal projection on another surface, and are shaped so that the projection on one element is pressed into engagement with a corresponding groove on the next adjacent element by the rollers as the antenna is extended, to form a connected antenna.
