Abstract (en)
[origin: EP0573971A1] In the case of an antenna having a plurality of dipole units which are arranged one above the other in a co-linear manner on a supporting tube, in each case consist of at least one dipole element, and are arranged inside a protection tube which consists of insulating material and has an internal diameter which is small in comparison with an operating wavelength, a conductive decoupling surface is arranged, at right angles to the protection tube axis, between at least two dipole units which are arranged one above the other, the outer edge of which decoupling surface extends radially at least as far as the dipole elements and at most as far as the inner wall of the protection tube, and which decoupling surface is conductively connected to the supporting tube or to a reflector of the dipole unit. <IMAGE>
