          +When used with a repeater, a Wi-Fi antenna can connect to a desktop computer and can also be used with a phone. However, you need to know the router password and configure settings on the phone.

          +It should not be too far from the router, generally no more than 3 meters. You can also connect directly to the router with an Ethernet cable. 

          +

          +In obstacle-free conditions, the transmission distance can reach 200–300 meters. 

          +

          +In other words, the receiving distance is short, while the transmitting distance is long.

          +

          +When used with a USB Wi-Fi adapter, a Wi-Fi antenna is suitable for laptops or desktop computers (not suitable for phones) and can receive Wi-Fi signals over long distances. In obstacle-free conditions, the range can reach 200–300 meters.
