The invention relates to a structure comprising an enclosed antenna system, and a radome ( 18 ), where the structure comprises: a tower (B, C), comprising a main tube ( 2 ) fastened on a bottom flange ( 7 ) of the tower (B, C), a smaller-diameter tube ( 5 ) which hooks within the main tube ( 2 ) and further is fastened on an upper flange ( 8 ) of the tower (B, C), a nut ( 6 ) fastened on the other end of said smaller-diameter tube ( 5 ), a rod ( 3 ) which screws on within the nut ( 6 ), a shaft ( 4 ) fastened at the bottom part of the rod ( 3 ) and terminating in a nut ( 1 ), where the radome ( 18 ) is fastened on the upper flange ( 8 ) of the tower (B,C), thus making it possible to check the antennas mounted on the main tube ( 2 ) by that when screwing the nut ( 1 ), the radome ( 18 ) is arranged to move upwards, making the bottom of the antenna system accessible.
1. Structure comprising an enclosed antenna system, and a radome, wherein the structure comprises:
a tower, comprising a main tube fastened on a bottom flange of the tower, a smaller-diameter tube which fits within the main tube and further is fastened at one end on an upper flange of the tower, a nut fastened on the other end of said smaller-diameter tube, a rod which screws on within the nut, a shaft fastened at the bottom part of the rod and terminating in a second nut,
wherein the radome is fastened on the upper flange of the tower, thus making it possible to check the antennas mounted on the main tube by screwing the second nut, wherein the radome is arranged to move upwards making the bottom of the antenna system accessible.
2. Structure according to claim 1 , wherein the structure further comprises filters and/or low noise amplifiers.
3. Structure as claimed in claim 1 , wherein the structure comprises all radiating and active systems of a mobile telephony station.
4. Structure as claimed in claim 1 , wherein the tower comprises a body and a top.
5. Structure according to claim 4 , wherein the body comprises a bottom flange, a lattice welded or screwed on the bottom flange, and further the bottom flange of the tower which is welded or screwed on the upper part of the lattice.
6. Structure according to claim 5 , wherein the bottom flange of the tower comprises holes for passing cabling from the top.
7. Structure according to claim 4 , wherein the top comprises the main tube welded or screwed on the bottom flange of the tower, the smaller-diameter tube which hooks within the main tube and which further is welded or screwed on the upper flange of the tower, and the upper flange of the tower.
8. Structure as claimed in claim 1 , wherein an antenna is arranged to be able to be rotated relative to the main tube, either manually by unscrewing and screwing a nut or by using a motor which rotates the antenna.
9. Structure as claimed in claim 1 , further comprising a base.
10. Structure according to claim 9 , wherein the tower, comprising a top welded or screwed to a body, is arranged to be able to be rotated on the base for better orientation of antennas.
11. Structure as claimed in claim 1 , wherein the bearing part of the structure is made of aluminum.
12. Structure as claimed in claim 1 , wherein active systems reside in the interior of the body.
13. Structure as claimed in claim 1 , wherein the casing of the body is split in two sections for easy access to its interior.
14. Structure as claimed in claim 1 , the structure further comprising an enclosing part enclosing active internal parts, wherein the enclosing part of the structure is made from a synthetic material fully permeable by electromagnetic radiation and fully capable of protecting the internal parts against weather conditions.
15. Structure as claimed in claim 1 , wherein the radome is made from a synthetic material fully permeable by electromagnetic radiation and fully capable of protecting the internal parts against weather conditions.
16. Structure as claimed in claim 1 , wherein the radome is arranged to move upwards making the bottom of the antenna system accessible by that the main tube is arranged axially movable and rotatably fixed relative to the smaller-diameter tube.
17. Structure comprising an enclosed antenna system, and a radome, wherein the structure comprises:
a tower, comprising a main tube welded or screwed on a bottom flange of the tower, a smaller-diameter tube which hooks within the main tube and further is fastened at one end on an upper flange of the tower, a nut fastened on the other end of said smaller-diameter tube, a rod which screws on within the nut, a shaft welded at the bottom part of the rod and terminating in a second nut,
wherein the radome is welded on the upper flange of the tower, thus making it possible to check the antennas mounted on the main tube by screwing the second nut, wherein the radome is arranged to move upwards making the bottom of the antenna system accessible.
