Abstract (en)
[origin: EP0307351A1] The directional and emission characteristics of horn antennas are intended to be adjustable on the horns themselves. To this end, at least one wall section (21) of the funnel shape of the antenna is itself adjustable relative to a further wall section (22) on the antenna (30). In one design, the wall sections are formed by funnel walls which are arranged telescopically and can move relative to one another in the axial direction. Other designs provide funnel walls which can pivot. <IMAGE>
