I was going to guess the same reason before I clicked the link and it confirmed it.

It may help to prevent people who are less knowledgeable from simply hooking something up not intended by the designers or FCC regulations. Obviously not impossible, but it requires more know how and/or effort to make a connection. Some people will just look at it and say "darn, this won't fit" and give up on the idea. If that happens, the intent of making it different worked.

If we are asking random goofy RF history, why do they call it a "UHF" connector? (Nothing to do with trains, but it's a ham radio thing. I always called them PL-259/SO-239 to be clear)
