First, explain the concep時新t of a booster anten河外na. An antenna is a p笑個assive medium that radiates 身麗energy. It does not generate電信 or amplify energy. Similar 大有to visible light, if an o有下rdinary light bulb is used習電, it will be emitted 問西evenly around, and it will be 他海darker at a long distance. 校愛But if the same power 制來of light is transmitted with a報農 laser, the transmission distance can b算件e greatly increased.能煙

The same is true for gain antennas. A h吧白igh gain antenna can ma跳花ke the wifi signal (energy) mor可雪e concentrated. For general outdoo吃業r point-to-point wireless 窗南products, the antenn路地a gain can reach as 鐘謝high as 30dBi. In contrast, the他多 general antenna gain of ordina到窗ry home routers is only 3,4dBi. 他哥. But with such a high antenna 司海gain, the communication distance c用微an reach the level of te是自ns of kilometers. Bu放冷t this also brings a problem, that i錢又s, it is extremely sensitive 下著to the installation location. As long a窗光s the user end position is moved sl吧票ightly, the user end wifi signal will b商技e significantly reduced可森. Therefore, when installing such p從他roducts, you need to carefu煙看lly adjust the position and來費 adjust the angle.

The signal strength is good if the l相弟ocation is well selected, but the signa鄉來l becomes bad if the location move低黑s slightly. In short, 間低the higher the gain of the booste身鐘r antenna, the more sensitive the p水他osition is.
