Why bother with a rotating dipole... we've use a simple inverted vee for
Field Day for years, and 40M is a bottomless pit of contacts.
Directivity is hardly an issue at a height of 30-40 Ft. Crossed dipoles
are unlikely to result in significant gain. I suspect it's mental... if
you have confidence in the antenna it seems to work well.... the power
of positive thinking ;-)
