Mad Men TVs

[Robert Grant]

The fourth one looks a little like a 1959 GE 21T2425 I had watched decades ago, though the knob panel under the channel selector looks different (and a little newer).

None of the sets look obviously post-1963, but it is a little too dark for me to tell.

About bad rabbit ears reception:
A TV show or movie will often alter image or sound to remind the viewer that the show is set in the past. It is not uncommon to see vintage color footage de-colorized and scratches added, or an old record player or radio that had decent fidelity portrayed with audio that's been fed through filters to sound like a telephone.
However, anywhere at ground level in Manhattan (with the possible exception of Central Park), rabbit ear reception would certainly be miserable (the signals could be strong, but you would have multipath problems up the wazoo).
In the other areas of the city, full of brick and brownstone row houses, rabbit ears wouldn't work so well either.
But I can assume that thousands of viewers in wood frame houses on Staten Island would have had excellent reception with rabbit ears.

My own personal experience in the day, two Detroit single family homes, both 15-20 miles from the transmitters: one was a brick-to-belt bungalow, set in first floor living room, no UHF tuner - all four VHFs came in perfectly in all weather conditions. The other was a two-story brick colonial with like houses seperated by narrow driveways, RCA CTC-38 with rabbit ears and loop on first floor - VHFs usually fine, household appliances would mess up channel 2, UHFs iffy. In windy weather, 7 could suffer some fading, and UHF was hopeless.
