Definitions

  • the present invention relates to the field of support systems for antennas and specifically a system of fine antenna aiming adjustment with three orthogonal axes.
  • the aiming system which is the object of the present invention was conceived mainly for operating on integrated antenna & equipment radio systems even though it can be employed in systems with equipment in a remote location.
  • antenna aiming systems an important problem to be solved is to provide in all cases an antenna system easy to install and repair, i.e. allowing operation with the fullest ease and safety in field installation and repair.
  • Another problem is implementation of an aiming system which would facilitate as much as possible setting and adjustment operations and especially those of fine antenna aiming adjustment along three orthogonal axes to make accessible the adjustments on the antenna-support side and then the rear side of the antenna.
  • various types of antenna aiming adjustment but none capable of ensuring fine adjustment of antenna aiming along all three orthogonal axes and making accessible the adjustments on the antenna-support side and then on the rear side of the antenna.
  • the purpose of the present invention is to solve all the above mentioned problems and indicate a system of fine antenna aiming adjustment using antenna supports directable along three orthogonal axes, whose aiming is adjustable both roughly and finely by means of the appropriate use of setting and adjustment screws.
  • the various components can be directed mutually by screws which can run in slots or slits made in the components.
  • the present invention has for its subject matter a system of fine antenna aiming adjustment along three orthogonal axes, as better described in claim 1 and subsequent claims.
  • This configuration of the antenna support system allows achieving adjustment of the antenna along three orthogonal axes corresponding to elevation, azimuth and polarization by rotation of screws and/or turnbuckles arranged in positions easily reached from the rear of the antenna. Specifically, the elevation and azimuth are found in this configuration by means of side-by-side and hence easily used controls.
  • Fine adjustment of polarization finds particular advantage in those radio systems operating on crossed polarization and in particular those adopting the frequency reuse technique.
  • FIGS. 1A and 1 B show, with reference to the antenna support, a side and a top view respectively of the antenna aiming system
  • FIGS. 2A, 2B and 3 show three section planes of front views of the antenna support bracket indicated by reference number 1 on three planes perpendicular to the axes E-E of FIG. 1 B, and
  • FIGS. 4A, 4B and 4C show respectively two mutually orthogonal side views and a top view of a variant embodiment of the antenna azimuth control system.
  • the antenna 21 is rigidly set by screws 20 to a support bracket 1 which is in turn connected to an antenna supporting pole 22 of the entire system through an interface element 2 consisting of: a jaw 3 connected to the antenna supporting pole 22 by a pair of U-bolts 4 which surround the pole like a band, a round flange 8 which couples to the support bracket 1 through screws 11 which in the example described here are four in number, and in its central part two perpendicular ribs which unite on one side of the jaw 3 and on the other to the round flange 8.
  • the support bracket 1 comprises two orthogonal parts, one on which engages the antenna 21 and the other on which engages the round flange 8, with reinforcing ribs if desired between the two parts (sectioned in FIG. 1 B).
  • the flange 8 is provided with teeth 9 (better seen in FIG. 2B) which mesh with a screw 6 which can rotate in two seats 10 (of which a detail is shown in FIG. 2B) integral with the support bracket 1 around an axis having a direction orthogonal to the axis E-E (elevation axis).
  • the two seats indicated by 10' have the same function as the seats 10 but are used as an alternative if the antenna is installed in the position symmetrically opposite the antenna supporting pole 22 so that a single type of interface element 2 can be used in both cases.
  • the support bracket 1 is provided with a number of threaded holes 17 (more numberous than the screws 11) to allow setting of the interface element 2 by means of the round flange 8 and the screws 11 which are inserted in four of the threaded holes 17.
  • a number of threaded holes 17 more numberous than the screws 11 to allow setting of the interface element 2 by means of the round flange 8 and the screws 11 which are inserted in four of the threaded holes 17.
  • a turnbuckle 7 fixed on one side to the support 5, which is in turn rigidly connected to the pole by a U-bolt 14 under the jaw 3, and on the other side to the jaw 3 of the interface element 2.
  • Rough azimuth adjustment is achieved by manually rotating the support bracket 1 around the antenna supporting pole 22 after loosening the U-bolts 4 while using the support 5 to hold up the antenna system.
  • the azimuth adjustment system thus uses two components 3 and 5 which are both attached to the pole and engaged one against the other and are tightened or loosened alternately and made to run against each other.
  • the variant just described has the advantage of being usable with poles of different diameter thanks to the special pole attachment (the U-bolts).
  • rotation around the antenna polarization axis P-P is achieved by loosening the screws 20 for fixing the antenna to the support by turning the screw 16 or the screw 18, depending on the desired direction.
  • the azimuth adjustment system can be provided as shown in FIGS. 4A, 4B, 4C.
  • the jaw 3 and the U-bolts 4 of FIGS. 1 A, 1 B are replaced by a jaw 24 which is tightened on the supporting pole by means of a counter-jaw 25 and the screws 26.
  • the jaw 24 and the counter-jaw 25 have a central inner groove in ring form shown in broken lines in the FIGS..
  • the counter-jaw 25 has a central through slot 32 in whose sides are provided two ribs for support of the screws 27 and 28, which can be fitted if necessary with lock nuts.
  • the support 5 and the U-bolts 14 of the FIGS. 1A, 1B are replaced by a ring consisting of two parts 29 and 30 connected on one side by a pin 31 and on the other side, by means of appropriate side-by-side protuberances, using the screws 33.
  • the screws 27 and 28 buck on the sides of these protuberances.
  • the two parts 29 and 30 are opened to allow wrapping around the pole to which they are rigidly fastened by the screws 33. Then the jaw 24 and the counter-jaw 25 are mounted on the pole in such a manner that the ring formed by the two parts 29 and 30 remains in the central groove and the protuberances of the parts 29 and 30 emerge from the slot 32.
  • the polarization adjustment system by means of the screw 16 and 18 can be replaced by a turnbuckle of the type indicated by reference number 7 in FIG. 2A and appropriately anchored on one side of the support bracket 1 and on the other to the antenna 21 , if necessary through a reinforcing rib of the type indicated by reference number 19 in FIG. 3.
  • the round flange 8 and the support bracket 1 can be interchanged to provide the teeth 9 of the support bracket 1 and the seats 10 and 10' for the adjustment screw 6 on the round flange 8.
  • the support bracket 1 and the rear part of the antenna can be interchanged to provide the supports for the adjustment screws 16 and 18 on the rear part of the antenna, and the reinforcing rib 19 on the support bracket 1.
