Antenna gain is a parameter that reflects an antenna’s capability to radiate electromagnetic waves in a specific direction. The higher the gain value, the stronger the antenna’s signal transmitting and receiving capacity in the targeted direction, and the wider its corresponding coverage range. However, it is worth noting that higher gain does not always equal better performance, as it may bring adverse impacts such as intensified signal interference and increased multipath effects.

Generally speaking, select a suitable 4G antenna gain under the following conditions:

1. Coverage Range

If you need to cover a large area such as large buildings, warehouses or outdoor sites, a higher-gain antenna is more suitable for extending signal transmission distance.

2. Signal Quality

If you suffer poor signal quality or work in environments filled with obstacles and electromagnetic interference, an antenna with moderate gain can strengthen signal reception and improve communication quality and stability.

3. Distance Requirement

For long-distance communication and remote connections, antennas with slightly higher gain deliver superior signal transmission performance.
