Abstract: A multi-antenna mounting device includes: a mounting member to which two or more antennas are fixable; and a tilt angle adjusting mechanism including an upper adjusting component and a lower adjusting component spaced apart along a length direction of the mounting member. The upper adjusting component includes a plurality of tilt angle adjusting holes arranged in a row, one end of the upper adjusting component is connectable to the mounting member, and the other end is connectable to a user's support pole with a fastening element extending through one of the tilt angle adjusting holes. When the fastening element extends through different tilt angle adjusting holes, the multi-antenna assembly has different mechanical tilt angles relative to the support pole. The lower adjusting component includes a first section and a second section. The second section has a predetermined length and the first section is pivotable relative to the second section.

Abstract: Printed circuit boards suitable for base station antennas have a first through hole for receiving a conductor of an electrical connector and a first conductive trace for electrical connection with the conductor to transmit signals. The first conductive trace is provided on a first side of the printed circuit board and the electrical connector is located on the same side of the first conductive trace when mounted on the printed circuit board. The conductor is electrically connected to the first conductive trace via a bypass provided on a second side of the printed circuit board, opposite to the first side. The printed circuit board can be provided for a base station antenna that includes a calibration board including the printed circuit board. The printed circuit board can facilitate the good positioning of the electrical connector thereon, the good electrical performances, or can avoid a possible short circuit.

Abstract: Printed circuit boards for a base station antenna include a substrate layer, and a first conductive trace and a second conductive trace which are printed on the substrate layer and cross each other. The first conductive trace has two trace sections separated by the second conductive trace. Adjacent ends of the two trace sections separated by the second conductive trace are connected electrically by a jumper. The jumper has an electrical conductor, is isolated electrically from the second conductive trace and is fixed on the printed circuit board. The electrical conductor and the two trace sections are connected electrically at adjacent ends. The printed circuit board allows flexible wiring of the conductive traces on the printed circuit board.
