Abstract
The present invention relates to radio communications and in particular to antenna structures. There is a growing demand in the radio communication system market to reduce the size and cost of radio communication sites and to reduce the maintenance costs involved. Many radio communication sites are also costly and difficult to maintain especially when dealing with components of the antenna structures which are located near the top of the antenna structures. The present invention attempts to address these problems. The present invention provides an antenna structure comprising a hollow antenna mast having an inside and an outside, a movable module disposed inside the hollow antenna mast and a lifting mechanism. The movable module has at least one antenna and/or at least one RF module. The a lifting mechanism permits the raising and lowering of the movable module inside the hollow antenna mast. Furthermore, the communications equipment can be placed inside the hollow antenna mast.
