We use the K2KQ inspired vertical dipole at PJ4K for 160. Top's at
about 135 feet and bottom at 30 feet. We opted for this approach so
that there's no fighting the cactus to install ground-mounted radials.
If we can ever get back to the island, we have all the pieces ready to
put up a phased pair of these antennas.
If you decide to go with this antenna, make sure you consider effects of
the vertical supports. We ended up de-tuning our 140-foot towers.

For those who have limited space and are unable to lay out an effective ground
system, the vertical dipole offers a very worthwhile alternative to an
Inverted-L or low Inverted-V.
It is relatively easy to build, install, and tune. The K2KQ article has been
followed by hundreds with success.
Vertical dipoles on 160 meters have been in place at P40W and P40L for a decade
or more. Small footprint, vertical polarization and no ground system were the
design parameters that prevailed.
