What kind of antenna should be used when using a wireless bridge, and what should be paid attention to when implementing it?  

If the wireless bridge adopts point-to-point mode, both ends adopt directional antennas. Point-to-multipoint, the center point can be an omnidirectional antenna. When configuring, pay attention to the use of 5G antennas. The channels at both ends must be the same. Pay attention to the standardization of engineering installation. For example, wind resistance and grounding should be considered when installing antennas on poles.
