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.

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.
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.
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.
