<p>The device (7) for anchoring a mast which is intended to carry an aerial comprises a tubular ring into which the mast is intended to be inserted. A screw is adapted to be screwed through a threaded hole in the ring such as to cause the end of the screw screwed through the ring to exert pressure against the mast. The portion of the screw situated outside the ring extends through a suitably tubular strut (12) extending in a plane tangetial in relation to the ring. The screw extends through the strut (12) at one end thereof whereas the opposite end of the strut is provided with means permitting anchoring on the roof, wall or the like. Suitably, a nut is screwed onto the screw in a position between the head of the screw and the strut for clamping the strut between the nut and the ring. The length of the strut (12) is preferably adjustable. In the embodiment shown three anchoring devices are mounted.</p> |
