You know, you're right. I have a couple of radios that have no built-in antenna. Both are older radios, pre-WWII. Seems like after that, most AM radios have built-in antennas. I'm so used to internal ferrite coils on AM radios, sometimes I forget that not every radio has one.
If you don't hook up an external antenna on a radio without an internal built-in antenna, it will get absolutely nothing, not even the 50Kw boomer stations. But when you connect an antenna, they work great. I personally prefer loop antennas for MW (AM) radios, longwires for SW.
