Frequently Asked Questions (FAQ）
Q1: Does this antenna support the 5GHz band?
This model is optimized for the 2.4GHz band and does not support 5GHz. For dual-band coverage, we recommend pairing it with a separate unit.5GHz AntennaOr use a dual-band unified device.
Q2: Does a 19dBi gain mean a longer transmission distance?
Yes. High gain boosts effective radiated power and extends transmission range, but requires precise alignment and a clear line of sight. Actual distance varies based on environmental interference and transmit power.
and comprehensive impact on receive sensitivity.
Q3: Is it suitable for outdoor installation?
Yes. The main body is constructed from industrial-grade aluminum alloy with a rust-resistant design. An IP65 protective cover is available to withstand outdoor conditions such as rain, wind, and dust. A lightning protection grounding system is recommended.Moduleby
