Ainoastaan low band on varmuudella kykyjen ulottumattomissa.
"RWR/ESM part has coverage 2-6GHz (Band 3), 6-18GHz (Band 4) as a base and adds 0.5-2Ghz (Band 2) and 18-40Ghz (Band 5) for Block 4. "
Nuo band-numeroinnit on tosi vaikeita päätellä kun eivät tunnu seuraavan logiikkaa. Esim. alla Growlerissa menee vain 0-3.

The aircraft has radar warning receivers on the leading edge of its wings covering frequencies of bands 2, 3 and 4. Two band-3/4 RWRs are positioned close to the wingtips on the aft wing trailing edges and on the aft horizontal stabilisers, with additional RWRs covering band 2 either side of the aircraft’s exhaust. These provide the aircraft with full 360 degree coverage.
Although the aircraft is presently configured to detect RF emissions in bands 2, 3 and 4, there is growth potential for this to encompass band-5 threats in the future. Although no details appear to have been publicly released it is thought that the AN/ASQ-239 can detect hostile radars transmitting in a two gigahertz to 20GHz waveband. Enhancements to the AN/ASQ-239 are being performed via a series of block enhancements which confer increasing levels of capability onto the self-protection system.

Enhancements to the F-35’s electronic warfare systems will focus on software, firmware and hardware should be completed by 2024.

the EW antennae on F-22 only consist of band 3 and band 4 array, but that is enough for ALR-94 to cover the frequency range from 0.5-18 GHz so logically the band 2 EW antennae of ASQ-239 will be used to geolocate radar with lower frequency.

But also, the new emphasis on EA and SEAD has been borne of choices made by the Air Force itself, largely due to budgetary pressures.
Originally, USAF wanted to be an all fifth-gen force, with no need of Electronic Attack/SEAD. Then, it was a division of labor—fifth-gen for kicking down the door; legacy assets for day two and beyond,” Aboulafia explained. “But it’s increasingly clear that the Navy will have very little fifth-gen, and that they’ll need to cooperate. And given the F-15 procurement re-start, it’s clear that the Air Force will need to work with fourth-gen platforms in many roles for many decades to come.

"Many believe that stealth is perishable," says Teal Group's Richard Aboulafia, thus increasing the need for suppression of enemy air defenses. Of course, a key requirement for the F-35 is that it can take out advanced air defenses.
