Abstract

Claims (34)

1. A reflector antenna mount for a reflector antenna, comprising:

a primary mount coupled to a support arm; the primary mount rotatable in a first axis relative to the support arm;

a secondary mount coupled to the primary mount; the secondary mount pivotable in a second axis relative to the primary mount;

the reflector antenna coupled to a front side of the secondary mount;

a dielectric enclosure provided with a front face and a side surface coupled to the primary mount; the enclosure rotatable fixedly with the primary mount along the first axis; and

the front face spaced away from the reflector antenna, outside of a range of motion of the directional antenna in the second axis.

2. The reflector antenna mount of claim 1 , wherein the front face has a radius of curvature at least three times a radius of the reflector antenna.

3. The reflector antenna mount of claim 1 , further including a center portion on the front face generally in a shadow of a subreflector of the reflector antenna.

4. The reflector antenna mount of claim 3 , wherein the center portion is elongated in the second axis such that when the reflector antenna is pivoted through an extent of a range of motion in the second axis, a portion of the center portion remains generally in the shadow of the subreflector.

5. The reflector antenna mount of claim 3 , further including subreflector RF absorbing material on a front side of the subreflector.

6. The reflector antenna mount of claim 1 , further including a back plate coupled to the dielectric enclosure; the back plate partially closing the dielectric enclosure towards an electronics enclosure coupled to a back side of the secondary mount.

7. The reflector antenna mount of claim 1 , wherein the rotation of the primary mount is along a plurality of arc shaped primary slot(s) formed in the support arm, each having a radius of curvature around a primary centerpoint; a primary fastener coupled to the primary mount extending through each slot.

8. The reflector antenna mount of claim 7 , wherein a primary threaded rod pivotably supported by the support arm is threaded through a primary axis block coupled to one of the primary fasteners; the primary threaded rod driving the primary axis block to move the primary mount through the first axis.

9. The reflector antenna mount of claim 1 , wherein the pivoting of the secondary mount is along a plurality of arc shaped secondary slot(s) formed in the primary mount, each having a radius of curvature around a secondary centerpoint; a secondary fastener coupled to the secondary mount extending through each secondary slot.

10. The reflector antenna mount of claim 9 , wherein a secondary threaded rod pivotably supported by the primary mount is threaded through a secondary axis block coupled to one of the secondary fasteners; rotation of the secondary threaded rod driving the secondary axis block to move the secondary mount through the second axis.

11. The reflector antenna mount of claim 1 , wherein the enclosure has a constant thickness across the front face.

12. The reflector antenna mount of claim 1 , further including side surface RF absorbing material on the side surface.

13. The reflector antenna mount of claim 1 , wherein the dielectric enclosure front face extends longer in the second axis than in the first axis.

14. The reflector antenna mount of claim 1 , wherein the support arm is coupled to a second antenna enclosure.

15. The reflector antenna mount of claim 14 , further including an adapter cowling covering a space between the reflector antenna mount and the second antenna enclosure.

16. The reflector antenna mount of claim 14 , wherein the second antenna enclosure is aligned vertically with the reflector antenna.

17. The reflector antenna mount of claim 14 , wherein the second antenna enclosure is aligned horizontally with the reflector antenna.

18. The reflector antenna mount of claim 14 , wherein the second antenna enclosure is a second reflector antenna in a second reflector antenna mount.

19. A reflector antenna mount for a reflector antenna, comprising:

a primary mount coupled to a support arm; the primary mount rotatable in a first axis relative to the support arm;

a secondary mount coupled to the primary mount; the secondary mount pivotable in a second axis relative to the primary mount;

the reflector antenna coupled to a front side of the secondary mount;

an electronics enclosure of the reflector antenna positioned on a back side of the secondary mount, the electronics enclosure coupled to the reflector antenna;

a dielectric enclosure provided with a front face and a side surface coupled to the primary mount;

the front face spaced away from the reflector antenna, outside of a range of motion of the directional antenna in the second axis;

the front face having a radius of curvature at least three times a radius of the reflector antenna;

a center portion on the front face generally in a shadow of a subreflector of the reflector antenna; the center portion having a radius of curvature less than a radius of the reflector antenna;

the center portion is elongated in the second axis such that when the reflector antenna is pivoted through an extent of a range of motion in the second axis, a portion of the center portion remains generally in the shadow of the subreflector; and

a back plate coupled to the enclosure; the back plate partially closing the dielectric enclosure towards the electronics enclosure.
