摘要： A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

摘要： The present disclosure relates to a shock absorbing arrangement suitable e.g. for ship installed structures comprising a rod, a resilient member arranged in connection to the rod, a structure element and a locking member arranged in connection to the structure element. The locking member is arranged to detachably lock the structure element at a resting position at the rod and the locking member, or the structure element, is supported by the resilient member. The resilient member is configured such that a spring force of the resilient member acts to maintain the structure element essentially at the resting position at the rod. The locking member is further configured to release the structure element from the resting position when being exposed to a force exceeding a predetermined holding force, whereupon the resilient member acts to reinstate the locking of the structure element at the resting position at the rod. The present disclosure further relates to a shock absorbing structure comprising such shock absorbing arrangements.

摘要： A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna system includes a main reflector, a strut assembly coupled to the main reflector defining an antenna feed receiving area spaced from the main reflector, and a subreflector carried by the strut assembly and also spaced from the main reflector. The subreflector includes a frequency selective surface (FSS) material that is reflective for both a first frequency band and a second frequency band and transmissive for a third frequency band. First and second antenna feeds are arranged in a coaxial relationship adjacent the main reflector and directed toward the subreflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed at the antenna feed receiving area and directed towards the subreflector and the main reflector. The third antenna feed is for the third frequency band.

摘要： Improved radio-transparent communication tower panel security devices that can be easily mounted to and strapped around the cover panels of communication towers, including flag-supporting cellular communication towers, so as to band and secure the cover panels thereto and prevent them from falling off in high winds and/or other adverse weather conditions, while preventing wear and tear of flags and their lanyards. Preferably, the communication tower panel security device employs a flexible plastic tubing assembly and a connecting/tensioning assembly having first and second connector modules for safely securing radiation-transparent panels covering antenna service bays of a wireless telecommunication tower.

摘要： Antenna tower reinforcement configurations use bolted gusset plate and splice plate configurations that allow for increased clearance access using short threaded bolts and threaded gusset plate apertures for increased clearance access and/or ease of installation. The gusset plates are welded to the reinforcement plates rather than bolted. Splice plates are bolted to the gusset plates using splice bolts.

摘要： An antenna apparatus is provided which has a centroid close to a vibration isolation structure and which is hard to vibrate like a pendulum motion when vibration is applied. The antenna apparatus includes a first base plate, an antenna unit disposed at a side of the first base plate and supported by the first base plate, and a counter weight unit disposed at another side of the first base plate opposite to the antenna unit and supported by the first base plate. The antenna apparatus further includes a vibration isolation structure having one end fixed to the first base plate to suppress a vibration of the first base plate, and a second base plate to which other end of the vibration isolation structure is fixed and which is fixed to a moving object or a structural object.

摘要： An antenna unit part is coupled to a housing unit in such a way that the antenna unit part can be relatively oscillated. Acceleration sensors that detect accelerations that occur in an azimuth angle direction and an elevation angle direction are provided in the housing unit. Linear actuators are provided between the housing unit and an antenna unit part so that the linear actuators are able to adjust a relative angle of the antenna unit part with respect to the housing unit. A variation amount calculation unit calculates a variation amount in the elevation angle direction and the azimuth angle direction based on the accelerations detected by the acceleration sensors. A correction amount calculation unit calculates a correction amount to cancel the variation amount calculated by the variation amount calculation unit. The linear actuators are driven based on the correction amount.
