Abstract
Abstract A telecommunication antenna comprising a reflector rests on foundations through a support assembly comprising a metal structure to which the reflector is fixed at the upper end, and a circular ring at the lower end. The ring rests on the foundations by means of rollers whose axes are horizontal and connected to the foundations. The ring rotates about the horizontal axis of the antenna by friction from drive rollers whose axes are vertical and supported by foundations.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A steerable antenna comprising: a rigid antenna support structure, means rotatably mounting said support structure on foundation means about an azimuth axis of the antenna, a set of support rollers fixed to the foundation means, said rigid support structure having a substantially horizontal annular first bearing surface resting thereon, said rigid support structure including a second bearing surface in the form of a surface of revolution, guide rollers fixed to the foundation means and bearing against said second bearing surface to align the central axis of the first bearing surface in the azimuth axis of the antenna, said rigid support structure including a hollow body carrying on a lower face a circular rail which defines the first bearing surface and wherein a portion of the internal surface of said body defines said second bearing surface, and wherein said hollow body is frusto-conical and has on an inside surface an inwardly facing flange, one face of which defines said second bearing surface.
Claim 2
Dependent Claim
161 words
A steerable antenna comprising: a rigid antenna support structure, means rotatably mounting said support structure on foundation means about an azimuth axis of the antenna, a set of support rollers fixed to the foundation means, said rigid support structure having a substantially horizontal annular first bearing surface resting thereon, said rigid support structure including a second bearing surface in the form of a surface of revolution, guide rollers fixed to the foundation means and bearing against said second bearing surface to align the central axis of the first bearing surface in the azimuth axis of the antenna, said rigid support structure including a hollow body carrying on a lower face a circular rail which defines the first bearing surface and wherein a portion of the internal surface of said body defines said second bearing surface, and wherein said hollow body is frusto-conical and has on an inside surface an inwardly facing flange, one face of which defines said second bearing surface.
Claim 3
Dependent Claim
23 words
The antenna as claimed in Claim 1, wherein at least one of the guide rollers is motor-driven to provide an antenna steering drive.
Claim 4
Dependent Claim
177 words
A steerable antenna comprising: a rigid antenna support structure, means rotatably mounting said support structure on foundation means about an azimuth axis of the antenna, a set of support rollers fixed to said foundation means, said rigid support structure including a hollow body carrying on a lower face a circular rail which defines a first bearing surface of substantially horizontal annular form upon which rests said set of support rollers, a portion of the internal surface of said body defining a second bearing surface in the form of a surface of revolution, guide rollers fixed to the foundation means and bearing against the second bearing surface to align the central axis of the first bearing surface with the azimuth axis of the antenna, said hollow body comprising a cylindrical metal element having at its lower end a horizontal flange whose lower face defines the first bearing surface and an upper face which defines an annular third bearing surface and said antenna further includes retainer rollers fixed to the foundation means and bearing against said third bearing surface.
Claim 5
Dependent Claim
177 words
A steerable antenna comprising: a rigid antenna support structure, means rotatably mounting said support structure on foundation means about an azimuth axis of the antenna, a set of support rollers fixed to said foundation means, said rigid support structure including a hollow body carrying on a lower face a circular rail which defines a first bearing surface of substantially horizontal annular form upon which rests said set of support rollers, a portion of the internal surface of said body defining a second bearing surface in the form of a surface of revolution, guide rollers fixed to the foundation means and bearing against the second bearing surface to align the central axis of the first bearing surface with the azimuth axis of the antenna, said hollow body comprising a cylindrical metal element having at its lower end a horizontal flange whose lower face defines the first bearing surface and an upper face which defines an annular third bearing surface and said antenna further includes retainer rollers fixed to the foundation means and bearing against said third bearing surface.
Claim 6
Dependent Claim
23 words
The antenna as claimed in claim 3, wherein at least one of the guide rollers is motor-driven to provide an antenna steering drive.
