Definitions

  • the present invention relates to an antenna support for the direct reception of television broadcasts from a geostationary satellite.
  • the invention also relates to an antenna carried by such a support.
  • each television receiver can then be associated with a small antenna pointed at the transmitting geostationary satellite.
  • the antenna can be turned once and for all in the direction of this transmitting satellite. However, it is necessary to be able to adjust this antenna, in azimuth and in elevation, at the time of its installation, in a precise but simple manner so that this adjustment can be carried out by an inexperienced person.
  • the antenna support according to the invention is simple and economical and allows the user to easily adjust the azimuth and the site of this antenna during its installation.
  • the geostationary satellite telecommunication antenna support according to the invention is characterized in that it comprises: a steering pole fixed relative to the ground and able to rotate around its longitudinal axis to adjust the azimuth of the antenna, and an articulated quadrilateral of which one side constitutes a part of the antenna and another side is a part of the pole, the length of this part being adjustable and determining the site of the antenna.
  • the post is vertical.
  • the post can be fixed to a wall by means of flanges. It can also be fixed to another post driven into the ground also by means of flanges.
  • the lower end of the pole is introduced into a hole with a vertical axis of a base, this pole being able to rotate about its axis in its housing in the base, means being however provided for immobilizing said pole.
  • a paraboloidal antenna 10 is symbolized in FIG. 1A. This antenna is mounted on its support and the axis of its paraboloid reflector is pointed towards the transmitting satellite.
  • the support comprises a tube 1, the ends of which are clamped in collars 2. These collars comprise two parts in the form of an arc of a circle which are held around the tube 1 by tightening bolts.
  • One of the two parts of the collars 2 is integral with a foot 4 by means of which the collars 2, and therefore the tube 1 are fixed to a vertical wall 11.
  • the two half-flanges 3a have been shown in cross section, positioned around the tube using the two bolts 9.
  • the arm 7 of invariable length comprises two identical metal blades 7a. These two blades are at one of their ends, clamped one against the other between the two half-flanges by means of one of the tightening bolts 9a.
  • the two blades 7a are preformed so as to constitute an isosceles triangle, the apex of which is on the tightening bolt 9a and the base, the active line connecting the two ears 8a fixed to the rear of the antenna 10.
  • the ears 8a are integral with the antenna 10 at a predetermined distance from the upper ear 6, so as to preferably form an isosceles triangle whose apex is the upper ear 6 and the base, said fictitious straight line connecting the two ears 8a.
  • the ends of the metal blades are held on the lugs 8a by tightening bolts.
  • the arm 7 is articulated on the one hand to the flange 3 along a horizontal axis and on the other hand to the ears 8a of the antenna 10, along a horizontal axis 31.
  • Part 1b of the post 1 between the flange 3 and the arm 5 forms one side of a quadrilateral with three articulations 30, 31 and 6a whose three other sides are the arms 5 and 7 and the fictitious line connecting the ear 6 at a point on the axis 31. It is by varying the length of the part 1b that the axis 10a is pivoted.
  • the direction of the axis of symmetry 10a of the dish of the antenna 10 therefore depends on the position of the flange 3 on the tube 1.
  • the adjustment of the direction of axis 10a in a vertical plane that is to say of its site.
  • the tube 1 being able to pivot about its axis of symmetry, and the antenna 10 being integral with the tube 1 via the arms 5 and 7, this antenna 10 can pivot around the axis 1a. This pivoting of the tube 1 therefore makes it possible to orient the azimuth of the antenna 10.
  • the antenna 10 support is therefore initially fixed, by means of the feet 4 of the collars 2, on the wall 11, for example so that the tube 1 either in a meridian plane.
  • the installer can then act on the flange 3 so that the axis 10a forms with the vertical of the place where the antenna is mounted, an angle equal to the latitude of the location of the antenna.
  • the position of the axis of the paraboloid being linked to the position of the flange 3, it is possible to identify the position of this axis by graduating the tube 1 with marks 15, each mark corresponding to a precise position of the flange 3 and therefore from the site of the paraboloid axis.
  • a concordance table gives the reference 15 corresponding to the known latitude of the place where the antenna 10 should be placed.
  • the axis 10a of the paraboloid is in a plane substantially parallel to the plane of the equator .
  • the geostationary satellites being in the plane of the equator and at an altitude substantially equal to 36,000 km, it is possible to select the satellite to be received by rotating the antenna 10 around the vertical axis ie say the tube 1 inside the collars 2.
  • the collars 2 can be graduated so that a mark of this graduation corresponds to a transmitting geostationary satellite.
  • This adjustment can be refined by connecting the antenna 10 to a control receiver and by slightly modifying the initial settings so as to obtain the best possible image.
  • the antenna is immobilized by tightening all the bolts of the collars 2 and the flange 3.
  • FIG. 2 represents a second embodiment of the support according to the invention.
  • the support of Figure 1A is fixed via the feet 4 of the collars 2 on another post 16 which, in a preferred embodiment is of square section.
  • This post 16 is planted in a horizontal concrete slab 33. This embodiment allows for example the fixing of the antenna in a garden.
  • FIG. 3A represents a third embodiment of the invention.
  • the tube 1 provided with its arm 5 and its flange 3 no longer has a fixing collar, but at its lower end inserted in a base comprising a foot 20.
  • This foot 20 has a hollow cylindrical part 22 in which the tube 1 is positioned, this cylindrical part is held in a vertical position on a horizontal plate 23 by four support pieces 21. This foot is shown in top view in FIG. 3B.
  • the edge of the cylindrical part 22 is graduated by marks 17 equivalent to those arranged on the collars 2 of FIGS. 1A and 2, the tube 1 being able to pivot around its axis of symmetry inside this cylindrical part so as to adjust the azimuth of the antenna 10.
  • Tube 1 blocking means such as a stop screw, are associated with this cylindrical part 22.
  • the plate 23 is fixed to a horizontal slab 30.
  • These antenna supports therefore allow easy adjustment of the antenna 10 and are more particularly suitable, although not exclusively, for the installation of antennas intended to be oriented definitively towards the same satellite.
  • antenna support are more particularly suited to antennas for direct reception of satellite television transmissions.
