A tower or cupola-like covering for the protection of radio or television antennae against the weather is made in the form of a sectional casing with each section of the casing being attached only along its bottom or top edge to a supporting structure, with expansion joints between such edges that transmit no supporting forces. The construction eliminates compression or tension forces in the covering which might damage the same.

1. A tower or cupola-like covering for the protection of antennae for electro-magnetic radiation against the weather, the antennae being fastened to supporting structure within the covering and the latter being in the form of a sectioned casing of weather-resistant material permeable to electromagnetic waves, characterized in that each casing section is attached at a location remote from one of its edges rigidly to the supporting structure within the covering and with said one edge being movable relative to the adjacent edge of an adjacent section, and in that the sections have weather-excluding expansion joints therebetween which transmit no supporting forces. 2. Covering as in claim 1, characterized in that each expansion joint is bridged by at least one soft gasket. 3. Covering as in claim 1, characterized in that each expansion joint is covered up at least at its outside against penetration by weather by a covering ribbon. 4. Covering as in claim 1, characterized in that the adjacent edges of the sections are each covered up by a framing profile. 5. Covering as in claim 3, characterized in that the adjacent edges of the sections are each covered up by a framing profile and the the outside lateral wall of the framing profile on the top edge of each section extends below the slidably moveable, adjacent edge of the cover-up ribbon. 6. Covering as in claim 3, characterized in that one edge-parallel ribbon seal is provided at the opposite edges of each cover-up ribbon. 7. Covering as in claim 1, characterized in that both edges of each expansion joint are moveable in relation to the supporting structure. 8. Covering as in claim 7, characterized in that both edges have projections overlapping with a sliding surface therebetween. 9. Covering as in claim 8, characterized in that the sliding surface is developed between two slipbands attached to the respectively over-lapping opposed surfaces. 10. Covering as in claim 3, characterized in that the cover ribbon consists of a multiplicity of individual segment shaped cover plates which abut each other with beaded expansion joints. 11. Covering as in claim 10, characterized in that the expansion joints of the cover plates are displaced in relation to the expansion joints between individual sections of the casing. 12. Covering as in claim 11 including interengaging means on the one edge and on the supporting structure for restraining said one edge against lateral movement. 13. Covering as in claim 1 in which the one edge is one of the lower and upper edges of the casing section. 14. Covering as in claim 13, characterized in that there is a tower-like development of the casing with several coaxially superposed sections about an antenna mast comprising the supporting structure, said sections are supported by carrying mechanisms attached to the mast in several superposed planes, each section is attached rigidly to one of said carrying mechanisms and the one edge of each section is restrained to vertical relative movement by the expansion joint thereat. 15. Covering as in claim 14, characterized in that on the carrier mechanism supporting each section at least one vertical guide bolt is attached on which a reinforcement, attached to the upper edge of the adjacent section, is mounted slidably. 16. Covering as in claim 15, characterized in that the reinforcement has a guide casing which surrounds the guide bolt. 17. Covering as in claim 16, characterized in that the guide casing is lined with a plastic sleeve.
