Biggest issue I have with the solution proposed is the recommendation to avoid DFS channels. These channels are much more "cleaner" as adoption is less due to added cost caused by extra design and certification. Radars are pretty static and does not come and go (especially weather radars), so the router does not need to move from channel pretty much. False alarm can be an issue but if one has a decent quality router, it should not be very often. Furthermore, after a radar detection (false alarm or actual), routers can switch to non-DFS channels and and start operating immediately.
