  • Antenna drive
    Patent number: 4652887
    Abstract: An antenna is pivoted on a mounting about a first axis (3) and is driven by a screw threaded drive member (5) to which it is pivoted about a second axis (4). The drive member (5) engages a drive mechanism (6) which is pivoted about a third axis (7) all the axes being parallel. At one position of adjustment (illustrated) the second and third axes (4,7) are in line with each other enabling the drive member (5) to be pivoted to the position shown in broken lines thereby doubling the size of the arc through which the antenna can be rotated.
