In the US, it's only one specific type of weather radar (TDWR), which is only used at 45 major airports. If you don't live near one of those, you only have to worry about a false positive in the radar detection feature accidentally knocking you off a DFS channel. And I know from experience that local topography sometimes means you can be operating an AP on a DFS channel only a few miles from one of those airports without ever having a problem.

The military radar in particular runs anywhere they want at anytime without disclosing their actual location. The equipment itself also has false positives, which lead to much of it being unusable.
- Reason077 4y ago> "The equipment itself also has false positives" This has never noticeably happened in my experience (UK). I've used DFS bands on my routers for years. It's far worse to use non-DFS bands because if you live in a built-up area they are almost always congested, causing poor performance (latency spikes, packet loss, etc).
