The present disclosure relates to an antenna mounting device and a base station antenna system. The antenna mounting device includes a hinge device and an adjustment arm. The hinge device is configured to be mounted to a pole by a clamp and configured to pivotally connect a base station antenna arrangement. The adjustment arm is configured to be mounted to the pole by a clamp and configured to connect the base station antenna arrangement. The connection of the hinge device with the base station antenna arrangement is located in a middle region of a longitudinal extension of the base station antenna arrangement [having a longitudinal extension] of a maximum of ⅓ of the longitudinal extension of the base station antenna arrangement. A connection of the adjustment arm with the base station antenna arrangement is located in one of two end regions of the base station antenna arrangement. The adjustment arm has a plurality of connection positions for the corresponding clamp, which are configured to define a plurality of different mechanical tilt angles of the base station antenna arrangement about the hinge device. The antenna mounting device realizes easy adjustment of the mechanical tilt angle and good resistance against external disturbance loads.

Determining alignment and clear line-of-sight (LOS) of a satellite antenna using sensor data from an LOS sensor of the satellite antenna. Described techniques include storing first sensor data captured by the LOS sensor at a first time, the first sensor data indicating a first LOS condition of the satellite antenna corresponding to the satellite antenna having a beam LOS with a satellite of the satellite communication system that is aligned and unobstructed. The techniques may include receiving second sensor data captured by the LOS sensor at a second time after the first time, the second sensor data indicating a second LOS condition of the satellite antenna. The techniques may include determining an LOS condition change for the satellite antenna between the first time and the second time based on a comparison of the second sensor data with the first sensor data.

A microwave prism is used to repoint an operational Direct-to-Home (DTH) or Very Small Aperture Terminal (VSAT) reflector antenna as part of a ground terminal to receive (or transmit) signals from a different satellite or orbital position without physically moving the reflector or the feed horn antenna. The microwave prism operates by shifting the radiated fields from the horn antenna generally perpendicular to the focal axis of the parabolic reflector in order to cause the main beam of the reflector to scan in response. For an existing reflector antenna receiving signals from an incumbent satellite, a prism has been designed to be snapped into place over the feed horn and shift the fields laterally by a calibrated distance. The structure of the prism is designed to be positioned and oriented correctly without the use of skilled labor. This system allows a satellite service provider to repoint their subscribers to a new satellite by shipping a self-install kit of the prism that is pre-configured to have the correct orientation and position on the feed antenna to correctly re-point the beam at a different satellite once the prism is applied. One benefit of the system is that unskilled labor, i.e., the subscribers themselves, can be used to repoint a large number of subscriber antennas in a satellite network rather than requiring the cost of a truck roll and a technician to visit every site. The microwave prisms to implement this functionality can be constructed in different ways, with homogeneous slabs or blocks, Gradient-Index (GRIN), multi-layered dielectric, geometric or graded-index Fresnel-zone, metasurface, or metamaterial prisms. The geometric and electrical constraints of the design are determined by the incumbent and target satellites, and the ground terminal location.

A vehicle, vessel or airplane having an antenna and a motor rotating the antenna, a rotation encoder outputting information relating to the rotation and outputting the information to two controllers of which one controls the motor. The other controller receives the rotation information and information relating to a position/direction/axis in relation to the vehicle/vessel/airplane and outputting a second signal based thereon. The output of the second controller may be used for controlling the motor to have the antenna directed toward e.g. a satellite irrespective of the motion of the vehicle/airplane/vessel.

A mount main body for a parapet-hanging-type antenna is provided with a vertical support column part (or VSC part) that vertically hangs down along an outer wall surface of parapet. The antenna is installed to VSC part so as not to protrude upward from the parapet. A horizontal support column part (or HSC part) that bends and horizontally extends in a direction orthogonal to the parapet is provided at an upper end of VSC part. The mount main body is provided with a cylinder holding HSC part such that HSC part is movable frontward/backward along a central axis thereof and is rotatable about the central axis. VSC part is made pullable to an inner wall side of the parapet by rotating HSC part about the central axis, and moving HSC part to the inner wall side of the parapet along the central axis.

A fixing device capable of reducing a burden on an operator when adjusting an inclination of communication equipment is achieved. A fixing device includes: a first jig configured to fix communication equipment; a second jig configured to rotatably support the first jig about a rotation shaft; a ratchet mechanism configured to be capable of switching restraint or permission of rotation of the first jig in one direction with respect to the second jig due to weight of the communication equipment, and permit rotation of the first jig in another direction with respect to the second jig; and a biasing member configured to store biasing force when the first jig rotates in one direction with respect to the second jig due to weight of the communication equipment, and bias rotation of the first jig in another direction with respect to the second jig.

A remotely controllable antenna mount (100) for use with a wireless telecommunication antenna (102) provides mechanical azimuth and tilt adjustment using AISG compatible motor control units (171/192) and AISG control and monitoring systems to remotely adjust the physical orientation of the antenna. The mount control units are serially interconnected with AISG antenna control units (ACUs) (104) which adjust electronic tilt mechanisms within the antenna itself. An AISG compatible mount azimuth control unit (MACU) (171) drives rotatable movement of the antenna through a range of azimuth angle positions. The antenna mount further includes a mechanical downtilt assembly interconnected between the antenna interface and the antenna. An AISG compatible mount tilt control unit (MTCU) (192) drives a linear actuator for physical downtilt of the antenna through a range of tilt angle positions.
