I also notice when I run 'iw reg get' it still shows the format which
seems to support the antenna gain (N/A):
country US: DFS-FCC
        (2402 - 2472 @ 40), (N/A, 25), (N/A)
        (5170 - 5250 @ 80), (N/A, 16), (N/A)
        (5250 - 5330 @ 80), (N/A, 16), (N/A)
        (5490 - 5730 @ 160), (N/A, 16), (N/A)
        (5735 - 5835 @ 80), (N/A, 23), (N/A)

If this isn't supported by the .db anymore then maybe this format
should be updated in configuration utility. Am I on track? I'd be glad
to attempt a patch if this is of value? Thanks

Cheers,
