Fastening device and associated method

Abstract

A fastening device (10) for fastening an antenna (1) to a support (5) comprising: - a first element (10a) configured to be fixed on the support (5), - a second element (10b) configured for linking thefirst element (10a) to the antenna (1), -a first setting unit (16) for setting an angular orientation of the second element (10b) with respect to the first element (10a), wherein the first setting unit (16) comprises: - a first and a second pairs of holes (20a, 20b, 21a, 21b) made in one of the first or second elements (10a,10b), the holes (20a, 20b, 21a, 21b) of a pair facing each other, -at least one through opening (18) having an arced oblong cross-section made in the other of the first or second element (10a,10b), the at least one through opening (18) being configured to be placed betweenthe two holes (20a, 20b) (21a, 21b) of a pair, -at least a first and a second axles (22), an axle (22) being configured to be placed through both the holes (20a, 20b) (21a, 21b) of a pair and a through opening (18), -first tightening means (24) configured for blocking a relative displacement between the first and the second elements (10a,10b).

Description

Background technique [0001] The present invention relates to a fastening device for fastening an antenna to a support, and in particular a parabolic microwave antenna to a pole. [0002] In fact, in order to optimize the signal transmission between the transmitting and receiving antennas, both the transmitting and receiving antennas must be oriented in a specific direction called alignment. Therefore, the antenna must be fastened to a support such as a pole, and the fastening means must be able to be fastened and set in the correct orientation. [0003] Figure 1a to Figure 1c An antenna 1 and first fastening means 3 according to prior art are shown for fastening the antenna to a pole 5 . This first fastening means 3 comprises two separate parts, marked P1 and P2. First part P1 forming the first loop is tensioned to the pole 5 and the second part P2 is linked to the antenna and comprises the second loop over the first part P1 such that the first part P1 prevents the second p...

AI Technical Summary

Problems solved by technology

One solution to this problem would be to move the antenna 1 further away from the pole 5, but this solution would result in a larger wind surface area and a taller lever arm, which would lead to increased stress on the material, resulting in a higher Larger and therefore more expensive material and degradation of the signal due to movements and vibrations of the antenna 1 (under the action of the wind)
