No, it was not unique. Nor was it a size issue, but rather of cost & feature set. I recall buying for my parents in 1986 a top-of-the-line 20" Sony that had at least one (if not two) composite video and stereo audio inputs (for the VCR). So having only a RF input and no AV inputs in 1994 puts it as a basic or low-end TV.
But what kind of connections and sizes were used?
The original RF connection on television receivers was two screws for 300 Ohm twin-lead. Later as coaxial cable became preferred over twin-lead for carrying the RF signal (and the cableTV industry may have had some influence), the 75 Ohm "F" connector was used as the RF connector. BTW what everyone simply refers to as a TV is properly termed a "television receiver", as opposed to the modular approach of separate tuner, (display-only) monitor, and speakers (e.g. Sony's Profeel line).
When multiple video sources started to be used in the home (e.g. VCRs, video discs, game consoles), baseband video (aka composite or CVBS video) and stereo audio inputs (with input selection on the remote control) began appearing on TV receivers. These were typically marketed as "TV/monitors". These video and audio inputs (on USA consumer units) all used the cheap RCA (aka phono) jacks. (On professional video & broadcast gear the video connector was BNC.)
When JVC introduced S-VHS in 1987, they used a 4-pin mini-DIN connector that is now known as a s-video connector. When DVD was introduced in 1995, YPbPr component video (again) used the cheap RCA jacks. YPbPr inputs would probably only be useful on large and/or high-quality displays. Late in the game, digital input connections appeared (i.e. DVI for video and HDMI for video & audio).
I had a Sony 27XBR15 made in 1989 that had two RF "F" input connectors (ANT1 & ANT2) (plus a RF out), 3 set of AV inputs (L+R audio, composite video and s-video), audio line-out and external speaker terminals. A top-of-the-line 20" set five years later would be probably still be similar (no component video yet), with AV inputs on the front.
My 20" Panasonic TV was made in 1994, and only has a coaxial jack for stereo sound and RF video.
RCA plugs & jacks are not generally called coaxial connectors despite their shape. Or are you mislabeling a headphone jack (3-pole 1/4") or earphone jack (3-pole 3.5mm)? The RF connection is not just for video.
