First Claim
Patent Images
1. An enclosure for an open end of a reflector antenna, comprising:
- a substantially cylindrical shroud adapted to be coupled to a distal end of the reflector antenna, the shroud generally coaxial with a longitudinal axis of the reflector antenna;
a retaining band coupled to an inner diameter of the shroud, proximate a distal end of the shroud;
the retaining band provided with a retaining groove open radially inward towards the longitudinal axis;
a bottom of the retaining groove extending radially outward beyond an outer diameter of the shroud; and
a radome seated within the retaining groove.

Abstract
An enclosure for the open end of a reflector antenna includes a cylindrical shroud coupled to a distal end of the reflector antenna, the shroud generally coaxial with a longitudinal axis of the reflector antenna. A retaining band is coupled to an inner diameter of the shroud, proximate a distal end of the shroud. The retaining band is provided with a retaining groove open radially inward towards the longitudinal axis. The retaining groove provided with a bottom extending radially outward beyond an outer diameter of the shroud. A radome is seated within the retaining groove.

14. An enclosure for an open end of a reflector antenna, comprising:
-
a substantially cylindrical shroud adapted to be coupled to a distal end of the reflector antenna, the shroud generally coaxial with a longitudinal axis of the reflector antenna; an RF absorbing material coupled to the inner diameter of the shroud; a retaining band coupled to an inner diameter of the shroud, proximate a distal end of the shroud;
the retaining band formed by a plurality of interconnected arc segments;the retaining band provided with a retaining groove open radially inward towards the longitudinal axis; a diameter at the bottom of the retaining groove is greater than an outer diameter of the shroud by at least one width of the retaining groove; a bottom of the retaining groove extending radially outward beyond an outer diameter of the shroud; a radial inward edge of the retaining band has a smaller inner diameter than the shroud; and a radome seated within the retaining groove without contacting the shroud.

15. Method for assembling an enclosure upon an open end of a reflector antenna, comprising the steps of:
-
coupling a plurality of portions together to form a substantially cylindrical shroud; coupling the shroud to a distal end of the reflector antenna, the shroud generally coaxial with a longitudinal axis of the reflector antenna; coupling a plurality of arc segments together around a periphery of a radome to form a retaining band; the retaining band provided with a retaining groove open radially inward towards the longitudinal axis, the radome seated in the retaining groove; and coupling a mounting portion to an inner diameter of a distal end of the cylindrical shroud.
