Frequently Asked Questions

What is the difference between right and left circular polarization? Circular polarization is used to minimize the effects of multipath signal propagation. Right and left polarization differ in the direction of the electric field's rotation, allowing them to be used for channel separation and reduction of cross-interference.

Are additional cables needed for connection? The antenna comes with two inputs, to which coaxial cables (not included) must be connected. The choice of cables depends on your equipment and the length of the run.

Can this antenna be used for 5 GHz Wi-Fi? No, this antenna is designed for the 6.1-7.4 GHz range and will not work effectively at 5 GHz. For 5 GHz Wi-Fi, a suitable antenna should be chosen.

How to choose between the two circular polarizations? The choice between right and left polarization depends on your network requirements and the presence of interference. Often, both types are used for MIMO systems to improve performance.
