Description

Technical area

The present invention relates to an enveloping device for a cellular radio mast with the features of claim 1 and to a cellular radio mast for holding a plurality of transmitting antennas for cellular radio according to the preamble of claim 12.

State of the art

In the field of mobile radio technology it is known to use base stations as stationary devices for the transmission of radio signals, which base stations usually contain an antenna carrier for holding a multiplicity of transmitting antennas. A common embodiment of such an antenna support is a free-standing tubular steel construction. Since the antenna supports are sensibly set up in elevated and thus exposed locations, their technical character often stands out strongly compared to an environment. For this reason, for example, in urban areas, panels of antenna supports are used, which are slipped over the antenna support as a free-standing cover and can be designed as dummy chimneys made of glass fiber reinforced plastic. Such claddings require a considerable effort for the production of molding tools.

Due to the usually exposed location of the installation locations of antenna supports, the transmitting antennas are exposed to environmental influences and weather in an unprotected manner without using a cladding and must therefore be protected by housings with a specified IP protection class.

The technical field of cladding antenna supports, especially in mobile radio technology, therefore still offers room for improvement.

Object of the invention

The present invention is therefore based, in particular, on the object of providing a cladding of an antenna carrier, in particular for mobile radio technology, which has a simple construction, through which the effort to create Forming tools can be avoided, and which can be easily installed and designed and dimensioned in a flexible manner.
