Abstract (en)
[origin: FR2807214A1] The pylon includes an HF amplifier mounted in the top section, and a parallelogram linkage to maintain angular position. The radio transmitting mast comprises a pylon supporting at least one aerial, with equipment including an HF amplifier mounted in the upper part of the pylon. This equipment is mounted in a profiled box which is solidly attached to the pylon, and provided with power by photoelectric cells mounted on the upper part. The upper part of the pylon includes a rotary inertial mass, giving gyroscopic stabilization to the top of the pylon. At least a part of the upper pylon structure includes a deformable parallelepiped linkage, arranged so that the spars on which the aerials are mounted remain parallel to the ground, even when the overall structure of the pylon flexes. The parallelepiped linkage may be sustained by at least two tensioned cables.
