A couple years back I had an M2 2-el 40 on tower #2 at 128 ft and a lazy
vee vertical dipole 4 square for 40 meters on tower #1 below a TH-7 which
was at 123 ft. In A/B comparisons there was no clear winner between the
two 40 meter antennas. Which of the antennas was "slightly better" than
the other varied from night to night or the path involved.
Of course everyone on the reflector with a 2-el 40 told me there must be
something wrong with mine. But, none of those comments seemed to be
based on those people doing an A/B comparison. In the end maybe it
simply proved on can never have too many antennas on any band!
