I have a 90 foot vertical for 160 meters.

Yes, I have tried it on 60 meters. It seems to be
about equal to an inverted vee at 60 feet at long
distances. For short skip, as expected, the inverted
vee wins. It is over a VERY extensive ground screen.

A 90 foot vertical is the same as a 90 foot
dipole, except it is in a different orientation
and is fed at the end instead of in the middle.
Since the FCC rules do not address these distinctions,
AFAIK this is a regulation dipole into which
you can transmit 50 watts.

The FCC does require that you be able to show your calculations or
measurements to confirm that it is equivalent to a dipole (i.e. no gain).
