PowerBeam M5 works

WE set up a new Ubiquiti PowerBeam M5 300 ... it programmed with AREDN MESH no problems. It was connected it to a Mikrotik HAP-AC-Lite 5th port (PoE). It set up correctly, all parameters. The network found it. Then it connected to a stand-alone Ubiquiti Bullet M5 (once the frequencies were set to the same), and the network is tunneled.

We approve the PowerBeam M5, ... KK4IB and KC4JIR, Middle GA network [www.ga-aredn.lumasis.net; ga-aredn-users@groups.io].

We used 5740 MHz and wonder what frequencies are being used elsewhere.
