What is directional antenna technology???
Directional antenna can be compared to a torch, the direction of torch irradiation is the range and distance of directional antenna coverage, directional sky coverage needs to adjust the angle, its panel must be parallel to the coverage area.
And omni-directional antenna can be compared to the lights hanging from the top inside the home, the coverage is omni-directional, almost 360 °, but the coverage distance is not as good as the directional antenna.
