Definitions

  • This invention relates to mounting arrangements of microwave radio antennas and r.f. heads.
  • the guide channels comprise arcuate slots formed in a rear wall of the antenna casing (or in a front wall of the r.f. head), each slot having an enlarged end at which the corresponding stud of the r.f. head (or antenna casing) can be inserted or removed.
  • the wall portions around the slots are formed on an incline and shoulders of the studs engage the inner sides of these wall portions, so that as the r.f. head is turned into its secured position, the r.f. head is effectively pulled more closely against the antenna casing.
  • the studs carry elements which are spring-biased inwardly and thus against the wall portions behind the slots. The arrangement in accordance with this invention enables an operator to attach or detach the r.f.
  • a bracket arrangement which comprises two overlapping plates having a first bolt passing through them, the two plates being rotatable relative to each other about the first bolt, a second bolt passing through an arcuate slot in a first plate, one plate being formed with an arcuate slot having a toothed edge and the other plate being formed with an aperture located to correspond with said toothed-edge slot.
  • an O-ring 24 forms an environmental seal between the two waveguide ports.
  • each stud 26 carries a head element 27 which is biassed inwardly from the end 26a of the studs by a spring 28. Portions of the antenna casing wall 11 adjacent each slot are formed, as shown at 11a, to lie inwardly from and at a small angle to the plane of the wall 11, so that as the r.f. head 20 is turned into the secured position, the springs 28 of the two studs are progressively compressed: this has the effect of pulling the r.f.
  • Figure 6 shows a preferred form of adjustable engagement between any pair of brackets: this arrangement may be used to provide each of the three adjustments outlined above.
  • the two brackets which are to be relatively adjusted, comprise respective plates 60,70.
  • One plate shown here as the lower plate 60, has three circular apertures to receive bolts 61,62,63: the upper plate 70 has one circular aperture to receive bolt 61, and two arcuate apertures to receive bolts 62,63; thus, the plate 70 can be turned around bolt 61 relative to plate 60, and then the three bolts 61,62,63 tightened.

Abstract

Ensemble antenne à hyperfréquences qui comprend une tête (20) à fréquences radio-électriques montée amovible sur un boîtier (10) d'antenne et pouvant être attachée ou détachée d'une seule main par un opérateur. Ledit boîtier (10) est doté de fentes incurvées (14) et la tête à fréquences radio-électriques comporte des plots (26) qui s'emboîtent dans les fentes (14). L'extrémité de chaque fente (14) est élargie si bien que les têtes élargies des plots (26) peuvent être introduites dans les fentes lorsque la tête (20) se trouve dans une orientation particulière par rapport au boîtier (10). La tête (20) peut ensuite être tournée pour s'aligner avec le boîtier (10), les plots (26) coulissant le long des fentes (24). Pour détacher la tête (20) du boîtier (10), il faut tourner ladite tête (20) de manière que les plots (26) soient en alignement avec les extrémités élargies des fentes (14), ce qui permet d'enlever la tête (20).
