@rmi@cloudisland.nz So you’d need a USB dongle to a custom radio protocol to a battery powered keyboard. (Think old school wireless mouse with dongle.)
My guess is maybe ~20 years ago such a thing was findable, but likely not now.
Best option these days is probably an embedded device as USB HID device with a custom radio link to an embedded USB (or Bluetooth) host that understands HID. But I’d expect that to need to be 100% DIY, at both ends.
(Or very retro USB 1 keyboard dongle and radio keyboard.)

@rmi@cloudisland.nz in case you didn’t find it, there’s a ~2021 era list of 2.4GHz “RF Wireless” keyboards, with make / model and links. Unfortunately they don’t list range. “2.4GHz RF Wireless” is a reasonable search term to find keyboards with USB dongles (ie not just Bluetooth). But the ones that do specify range that I’ve found are still 10m or less. https://www.reddit.com/r/MechanicalKeyboards/comments/pkyx1w/my_comprehensive_almost_24ghz_rf_wifi_mechanical/
