What is the plural possessive of radio?

Oh, dude, it's "radios'." Like, you just add an apostrophe after the "s" when you want to show that multiple radios own something. So, if you're talking about the antennas on a bunch of radios, you'd say, "The radios' antennas are all tangled up." Easy peasy.
