Dear all,
Your support is appreciated as we installed a new E-Band link using RTN380H but when we try to apply the desired B.W "1000M" it starts to flap and restart every few seconds. Even after applying the licence on the RTNs the problem still exists and what we can only do is downgrade the applied BW to be 250M.

Hello,
To solve this problem you must redo the link budget with the exact GPS coordinates of the ends A and B.
It is necessary to increase the diameters of the antennas in the ends A and B while keeping the same frequency band.
Thanks

Hello, dear.
The device supports this feature, but I don't know your load and other setup parameters, so I can't tell if it's a device failure or an error in the setup parameters, you can contact Huawei's local representative office and an engineer will provide technical support for you!
