  • Telescoping antenna with actuating gear driven cable
    Patent number: 4520365
    Abstract: A telescoping antenna with remote control which is extended and retracted by means of a plastic wire (9) running inside the telescope is described. The wire (9) comprises cut-in slots (12) which are spaced at regular intervals all the way through and whose front surfaces (14a, 14b) are closest in the area of the neutral fiber of the wire (9). The teeth (16) of a driven toothed gear (10) mesh with the slots (12) and act practically only in the area of the neutral fiber on the wire (9) which as a result has a lesser inclination to break.
