Abstract: The invention relates to an arrangement that can be worn on the heads of members of a group. This arrangement comprises at least one banner (B1) with two side edges (B1a, B1b) and at least two items of headgear (K11, K12), each with at least one holding means (K11c, K12c) on an outside (K11b, K12b). The banner (B1) can be fixed on the holding means (K11c, K12c) via the side edges (B1a, B1b) in such a way that the items of headgear (K11, K12), and therefore also the members of the group wearing them, are connected to each other by the fabric (B1c) of the banner (B1).

Abstract: A collapsible antenna (10) comprises an elongate boom (12) having a main axis (14) and a plurality of elongate radiating elements (16) having respective first ends (18.1) and respective second ends (18.2). At least some of the elongate radiating elements are flexible and are mounted at the respective first ends to the boom in longitudinally spaced relation. Regions towards the respective second ends of the at least some of the elongate radiating elements engage a flexible rope (20). The flexible rope forms part of a frame (22) which is manipulatable relative to the boom between a first collapsed configuration and a second operative configuration wherein the at least some radiating elements are in an operative configuration relative to the boom.
