With low frequency radar signal supression, the effect of VHF +10dBsm might be negated.

Note that the B-2A is equipped with a Northrop Grumman AN/ZSR-63 defensive avionics suite, and its function was never described in public.



Indeed and also notice that applies the same (actually even more effectively) to the F-35.

The F-35 defensive suite (such as the AN/ASQ-239) working together with the AESA radar (AN/APG-81) gives the F-35 a standoff jamming capability similar to the dedicated airborne jamming platforms such as the EA-18 Growler.
The F-35 defensive suite can also geo-locate radar sources.
