ABSTRACT:
The disclosure relates to radioelectrical antennas and more particularly to the radomes for such antennas. The external face of the radome is fitted out with a device for the removal of streaming water that comprises gutters inclined downwards so as to recover the streaming water and remove it towards the lateral edges of the radome. A device of this kind prevents the collection of water towards the bottom of the antenna. The thickness of this collection of water has a detrimental effect on the precision of the orientation of the antenna pattern. Application in particular to antenna radomes for aircraft landing assistance elevation stations or for plane radar antennas.
