Id like to think that many of the OT's that worked the band under the old
power restrictions found many suitable small lot antennas.
A look thru the old QST's, CQ, Radio, HRM, etc likely will show a few.
In the 50's I used a 80M dipole fed with 72 Ohm twinlead tied together at
the rig on 160; the Johnson Viking I loaded it and I made many contacts
including AM mobiles.
In the 60's I used what would later be called a half sloper and in the 80's
I worked coast to coast with 100W to a 750' Beverage just for grins and
giggles to see if it was possible after reading a QST artcle about the
Canadian government using an array for a ZL link on a higher frequency. It
was reported as more reliable than conventional antennas.
