  • Patent number: 4490726
    Abstract: A parabolic, collapsible rooftop microwave antenna for direct satellite-to-consumer TV transmission pivots in the direction of the aperture axis about a horizontal pivot axis in response to excessive wind forces. The antenna has a cross-head theodolite-type mount adjustable for azimuth and elevation, with a horizontal pivot that provides axial displacement if the axial wind force exceeds a predetermined threshold force. This limits the torque transmitted to the roof on which the antenna is mounted to a reasonably low level. Various torque sensitive horizontal pivots are described including a torqued pivot bolt, torqued slide bolts disposed in arcuate slots for limit-stop action, shear pins for quick release action, and biased springs for collapse and self-restoration to the initial vertical position in response to transient wind force exceeding a threshold force set by the spring bias.
