wifi antenna 6 dbi antenna 2400-2500mhz wireless module high gainn antenna When the directional gain of the antenna decreases by 3dB, the corresponding frequency range of the antenna. Any antenna has a band operating range. Different technologies, such as 1G, 2G, 3G, 4G, 5G, 6G. The farther the high gain antenna transmits the signal, the antenna produced by the company can be designed and produced according to the 1-38dBi gain
