Abstract:

An articulated linkage is disclosed for supporting waveguide and electrical cabling through a predetermined range of movement. The linkage comprises a plurality of elongated rigid sections, joined by articulated joint sections. The joints comprise at least two short links which are pivotably connected to each other and the adjacent rigid sections. Travel limit pins are provided to limit the pivoting motion of the joint links relative to each other and the rigid sections. The lines of waveguide comprise respective sections of flexible waveguide passing through the flexible joints of the linkage and are connected to elongated sections of rigid waveguide which are supported by the rigid sections of the linkage. The travel limits on joint movement are selected to limit the angular excursions to protect the flexible waveguide from undue stresses during movement of the linkage. The linkage allows continuous connection of the waveguide and cabling throughout the raising and lowering of an antenna group or other microwave utilization device.
