However, if it had a garden-variety RF amp tube such as a 6GK5, 6HA5 or other small-signal tube, I can see the need for a large antenna

My 1951 16" Philco uses a 6CB5 rf while the 1953 17" set uses a 6BQ7. Both have 4 video IF stages... the 1953 set is noticeably more sensitive than the 1951 and was a decent fringe area/Dxing set.
