In the early 60's I had a full size 40M vertical on top of a 70' pine tree
with a bunch ....maybe 8-10...of radials tossed over the branches and
weighted with lead fishing sinkers.
It was a superb DX antenna compared to a dipole about 40' high.
Its only fault is that it heard so well it turned the Drake 2B's front end
to mush. Thats when I bought a used 75A4 and rebuilt it at work to be near
bullet proof and still use it when the going gets tough on 160 CW.

Not on Topband, but I rigged a vertical dipole for 40M in one of my tall
redwoods with the top insulator up about 100 ft. It worked, but not very
well, not nearly as well as the horizontal dipoles at the same height.
If I had ONLY a single skyhook for an antenna that needed to work ABOVE
160, I would use it to hang either a traditional vertical over radials, or
an inverted Vee. On 160, it would definitely be a vertical over radials.
BTW -- a half wave dipole for 160M is about 260 ft.
