A WiFi antenna is a device that transmits and receives wireless signals to facilitate communication between devices and a wireless network. It plays a crucial role in determining the strength, range, and stability of the wireless connection.
How to Choose Your Right WiFi/WLAN Antenna
Remember that the choice of WiFi/WLAN antenna depends on your specific needs and requirements. It is important to choose an antenna that is compatible with your WiFi/WLAN receiver and provides the necessary performance for your application. Here are some factors to consider when choosing a WiFi/WLAN antenna:
- Frequency: WiFi/WLAN signal frequency ranges from 2.4 GHz to 2.5 GHz and 4.9 GHz to 5.8 GHz. That means a 5G antenna can be used as a 2G or 3G antenna.
- Directionality (omnidirectional or directional) and gain: Omnidirectional antennas radiate signals in all directions. They are suitable for general coverage. Directional antennas focus signals in a specific direction. They provide higher gain and are ideal for long-range connections. The gain of the antenna determines the sensitivity and range of its received signal. A higher gain antenna can receive weaker signals.
- Cable and connector type: WiFi/WLAN antenna cables, primarily coaxial cables, are wires used to transmit signals from an antenna to a receiver. Some cables can be used to connect a device with an external antenna or even an internal antenna installed within a separate device. The connection cable should be as short as possible to avoid possible signal loss. The connector type should meet the specs of your receiver device.
- Mounting: WiFi/WLAN antennas can be installed in different ways: wall mounting, pole mounting, magnetic mounting, adhesive mounting and screw mounting etc. In all cases, it is important to face the mounted antennas towards the sky for best results, and the antenna cannot be covered or blocked by metal plate in direction for receiving signals.
