One important reason for UHF for the Sup'R'Mod, instead of channel 3/4: Some TVs at the time had a built-in VHF antenna, and no external connection for VHF! But, the UHF was a small loop or "bowtie" that connected to a pair of screw terminals on the back of the set. For example, the 17"?

They were available with a variety of connectors. Some of those switchboxes had a short flat wire with spade lugs as output for connecting to the TV, and for input had screw terminal antenna input, and RCA for the RF input from the RF modulator. the Wikipedia article for the Sup'R'Mod II has a

Composite will 99.99% of the time be better than RF modulated due to the bandwidth of NTSC (American) Televisions.  The NTSC television standard was not what I would exactly call high tech or high resolution.  It was 525 scan lines interlaced at 30Hz meaning that there was only 262.5 lines
