First, explain the conce<​pt of a booster antenna. An ant¥♣↑enna is a passive medium that radiates energy. It≠φ does not generate or amplify energy. Similar‌↔≤ to visible light, if an ordinary light bulb is↕♣& used, it will be emitted evenl‌¥'≤y around, and it will be darker at×≤• a long distance. But if t↓♥®he same power of light is transmitted with✘§∑ a laser, the transmission distance can be great ✘§ly increased.

The same is true for gain antennas. A high>¶® gain antenna can make th↓€e wifi signal (energy) ‍±¶±more concentrated. For general outdoor point-↓→​↑to-point wireless products, the antenna ¶★πgain can reach as high as 30dBi. In contrast±∏', the general antenna gain of ord↓β&₩inary home routers is only 3,4<¥dBi. . But with such&δ$ a high antenna gain, the communi§©₹∑cation distance can reach t "™✔he level of tens of kilomet£∑ers. But this also brings <≥€εa problem, that is, it is extreme×→∏ly sensitive to the installation locat↑>₽₽ion. As long as the user end position φ‍¥is moved slightly, the use "₽r end wifi signal will be significantly ≥©δ↓reduced. Therefore, when installing such pr★♥ ♥oducts, you need to carefully adjust theγ↓δ position and adjust the angle.

The signal strength is good if the loca←&β÷tion is well selected, but the signal b≥‍✘≤ecomes bad if the location moves sl‍¥εightly. In short, the higher the gai≥σ♣§n of the booster antenna, the more sensitive × the position is.
