They really should open up a database system where you, or the radio itself,
registers to GPS location it’s operating at and enables/disables the use DFS
frequencies entirely.
But that would mean someone in the government would have to do some work, or
contract it out for one gagillion dollars…
Also, like said before, the best practice is to never use the radar frequency
in use near you.
The FCC doesn’t have enough man power to police unless it’s actually affecting
the radar system.
And therein lies the caveat. As I found out years ago, you can be clean or
operating DFS appropriate channels even outside the radar advisory distance,
and still get caught up in a witch hunt if SOME OTHER PROVIDER is causing the
problem.
When I had that go around, the FCC caught and fined a swath of WISPs because,
IMO, they couldn’t actually narrow down the abuser and just fined everyone that
was at all in any sort of violation of anything, in a 30 mile radius.

The nearest 5GHz TDWR station to us is over 400 miles away and on the opposite
side of the Sierra Nevada, yet we routinely get DFS hits.

I too am skeptical. The majority of our DFS detection's happen between 7am and
10am and only on northern facing AP's. The closest TDWR to us is 90 miles to
our south. I'm convinced our DFS events are false positives due to Cambiums
extreme sensitivity that showed up after firmware 15.0.3. Before that, almost
never a DFS detection. Now it happens on the regular, regardless of frequency.

I personally am skeptical that DFS actually works worth a damn, I think the
operable advice is DON'T USE THE SAME FREQUENCY AS YOUR LOCAL TDWR!!!!!!!
Even with DFS enabled. It's not had to look up the frequencies they use,
stay away.

What is the vert/horiz degree on those antennas or is it just one big
rotating parabolic dish ?
I imagine they would have hundreds of slim sectors of about 1deg each inside
a giant ball or dome.
