I'm not totally sure that those had been invented in 1948, but at least there is none here.

I think you are right about TV antennas back in the day also picking up FM. Indeed some TV's in 1948 (not this one) had continuous tuning that included the FM band.

Thanks for the suggestions!
They may have assumed the twin lead to an outdoor antenna
would act as a long wire. The other common thing on AM radios was an
air coil antenna built on the back. On Zenith consoles they used a big
air coil in a rotatable box. They were quite directional & the art work
was absolutely pissah. We had a mint late 30's Zenith in the window
& that thing could get stations like nothing else. I fired it up every morning &
put it on a big bands stations & the customers loved it. We refused
quite a few offers up to $500.

enuf fer now. I am getting carried away with memories.
