摘要:
An antenna fixing system (1) has a twistable lever arrangement for adjusting a tilting angle controlled by the two levers (3, 4). A joint (5) has a set of a first shell (6) having a first circular embossed elevation (7, 7', 7", 7'''), a second shell (8) having a second circular embossed elevation (9, 9', 9", 9''') and a clamping device (10) to exert a clamping force to the set. The first elevation (7, 7', 7", 7''') and the second elevation (9, 9', 9", 9''') correspond to one another in a contacting diameter range, the first and second shells (6, 8) are in a staggered manner such that the shells (6, 8) are in a surface contact, and a straight line (L), intersecting the joint axis (A) and tangentially touching the elevation, and a line (L') radially extending from the joint axis (A) enclose a predetermined angle (Θ).

A mechanical assembly provides an attachment of an antenna tower to an antenna that includes back ring attached to an antenna reflector. The assembly includes a horizontal beam and a bracket. The bracket includes a first, e.g . planar, portion and a second, e.g. planar, portion that meet at a corner. The first portion is configured to fasten to the antenna back ring and the second portion is configured to attach to the horizontal beam. The second portion includes a pivot slot for receiving a first fastener connecting the bracket to the horizontal beam, and includes a circular hole for receiving a second fastener connecting the bracket to the horizontal beam.

A user-terminal clamp that receives a user terminal of a satellite communications system, wherein the clamp clamps to a roof of a structure in either of two orthogonal orientations. The clamp includes a frame having a pair of movable clamping members that are actuated by a handle. The frame includes slots or channels that receive ribs that are disposed on the underside of the user terminal.

Ein Schachtantennensystem (1) zur mobilen Kommunikation umfasst ein Antennengehäuse (2), in welchem zumindest eine Antenne eingebracht oder einbringbar ist. Es umfasst außerdem einen Abstützrahmen (3), der eine Einführöffnung (4) und eine umlaufenden Wand (5) aufweist, durch die ein Aufnahmeraum (6) umgrenzt ist. Der Aufnahmeraum (6) ist von der Einführöffnung (4) aus zugänglich, wobei in ihm das Antennengehäuse (2) angeordnet ist. Eine Abschlussdeckelanordnung (7) verschließt die Einführöffnung (4), wobei die Abschlussdeckelanordnung (7) an ihrem Randbereich zumindest mittelbar an dem Abstützrahmen (3) abgestützt ist, so dass eine Unterseite (8) der Abschlussdeckelanordnung (7) eine Oberseite (9) des Antennengehäuses (2) überdeckt. Das Antennengehäuse (2) ist über zumindest eine Kraftspeichereinrichtung (10) zumindest mittelbar an dem Abstützrahmen (3) abgestützt. Die zumindest eine Kraftspeichereinrichtung (10) umfasst zumindest ein Schaummodul, das elastische, federnde und dämpfende Eigenschaften aufweist, wodurch die Oberseite (9) des Antennengehäuses (2) an der Unterseite (8) der Abschlussdeckelanordnung (7) angedrückt gehalten ist.
摘要:
An antenna stand for holding a flexible or non- flexible planar antenna includes a base and support frame. The support frame includes two spaced apart legs and a horizontal cross member interposed therebetween. At least two lower antenna supports are provided on the support frame on which the bottom edge of the planar antenna may rest. An optional extendable antenna holding arm includes an upper antenna clip that engages the top edge of the planar antenna. The extendable antenna holding arm support is adjustably mounted to the support frame so that the distance between the lower antenna supports and the upper antenna clip can be varied to accommodate planar antennas of varying dimensions. The support frame may be arcuately shaped transversely to impart a slight lateral bend to a flexible planar antenna mounted on the stand. This helps to maintain the flexible planar antenna in an upright position on the stand.
摘要:
There is provided an apparatus comprising a location receiver to receive a signal indicative of a location of the location receiver. A movement mechanism rotates the location receiver about an axis and provides an angle of the location receiver about the axis from a known point. Calculation circuitry produces an output value indicative of an absolute bearing of the known point about the axis, based on a plurality of given angles of the location receiver about the axis from the known point, and a plurality of associated locations of the location receiver indicated by the signal received when the location receiver is at each of the given angles.

摘要:
An assembly for a mobile communications antenna system includes a bracket assembly onto which an antenna array is mounted. The bracket assembly includes a steering arrangement configured to provide angular adjustment of an antenna beam azimuth, and an electromechanical tilting arrangement configured to adjust a tilt position of the antenna array. The steering arrangement and the electromechanical tilting arrangement are controllable in remote and manual operational modes to independently and variably adjust both azimuthal angle and tilt position of the antenna array. These operational modes ensure remote control of signal propagation and network coverage accuracy, and manual adjustment of the azimuth of the antenna beam and tilt position of the antenna array in case of field service or component failure.
摘要:
A clip for securing a radiating arm to a printed circuit boards of a radio frequency antenna element of a base station antenna. The radiating arm may be configured to receive signals or radiate signals from a feed network associated with the at least one RF antenna member. The radiating arm can be secured to the printed circuit board without the use of solder or adhesives.

A multi-panel antenna system may be disassembled and packaged into a container with substantially smaller dimensions than the assembled antenna system. The antenna system may include two or more reflector panels, such that a respective reflector panel can include a curved surface that may form a portion of a parabolic reflector, and can include an inter-panel fastener operable to align a side surface of the respective reflector panel with a side surface of another reflector panel. The antenna system may also include a mounting assembly that may be used to fasten a convex side of the two or more reflector panels to a surface external to the antenna system, and a feed assembly that may be attached to the mounting assembly.
