oh yeah, commercial weather radars are in this band as well.

These airport weather radars are able to work in 5670-5720 MHz.
In our country 5470- 5670MHz is open and 5670-5720 is not
allowed to use to avoid interference with these (it seems the same
type) airport radars.
Rocket in 5650 Mhz with 40 Mhz channel bandwidth has huge out of
band emission above 5670 frequency and create problems.

I seem to recall its coming up in a thread around then, but can't
find it offhand. However, it is tied to the TDWR issue, and in
August, WISPA and SpectrumBridge set up a TDWR database to help get
this fixed. So just this month, the FCC has started processing new
approvals for the 5475-5725 band. Good work on WISPA's part. Maybe
the UBNT radios will get the DFS needed to pass.
I don't really see why DFS is needed if you stay away from the
5600-5650 TDWR band, but that's the FCC for you... maybe there are
some other radars on the other frequencies though. That band is
legal in most other countries, so it's in the products. And of
course we Part 97 licensees can play (I do mean that literally, not
commercial use) with radios on all sorts of frequencies, like
5850-5875. ;-)
