Hi Mark,
You may well be correct---it was so very long ago that I can't recall (I'd only
been licensed myself but a coupla years at the time, too).
Zenon did what he did in order to get on 160-meters: he figured the notion of
placing the 1.8-MHz dipole / "V" like that above his HF rotary would (1) save
room on his city-sized lot, and, (2) give him the advantage of higher altitude.
I guess if one were to conduct some research into the Hy-Gain adverts in QST,
etc. from back then, one might actually get to see what this contraption looked
like...
