Beidou school server antenna installation precautions
August 17, 2023
1. When the server antenna of Beidou school is installed, first install the antenna head on the antenna bracket, and then fix the antenna bracket on the top of the building with expansion bolts. According to the installation conditions, the angle bracket (optional) can be used. The antenna head should be installed outdoors. The installation location should be wide open and installed on the roof as much as possible. In principle, the antenna head can look up to see the 360° sky. Then arrange the antenna cable from top to bottom. The turning radius of the antenna cable should not be too small. When piercing, pay attention to the connector. The length of the antenna cable is strictly designed according to the antenna gain, and the connector must not be cut, lengthened, shortened or installed. Otherwise, the receiving effect will be seriously affected and no signal will be received.
2. Antennas should avoid obstacles to the antenna beam such as hillsides, trees, high-rise buildings, towers, and high-voltage transmission lines. There should be enough horizon in the direction of the main beam of the antenna, and the widest possible angle of view should be in front of the antenna. The general requirement is to use the antenna base point as a reference, and the angle formed by the highest point of the obstacle is less than 10 degrees.
3. The erection position of the antenna should be avoided from the tuyere to reduce the wind load of the antenna. In the thunderstorm area, the erection position of the antenna should avoid lightning-prone locations, and the antenna head should be placed within the lightning rod lightning protection range of the power plant/substation. When the antenna is installed on the roof, as long as the view is sufficient, the distance from the roof is as small as possible. At the same time, the antenna should be equipped with a special lightning arrester as far as possible. Before the thunderstorm season arrives, it must be carefully checked whether the lightning protection grounding system is good or not.
4. The operating frequency of the server antenna of Beidou school is 1575.42MHz, and it should be installed as far away as possible from the nearby sources.
5. Do not insert or pull the connector of the server antenna during the Beidou school time to avoid damage to the circuit.
