Hi Walt.
So did the antennas that were set at right angles to each other. However,
I imagine that having a resonant element on 15 meters worked better than
loading a 40 meter antenna on its 3rd harmonic. It has been my experience
that a resonant antenna still beats a harmonically related antenna under
most circumstances. When I lived at my first location in East Bethany, NY,
I had separate resonant antennas for 40 meters and 15 meters. The 15 meter
dipole always outperformed the 40 meter dipole on 15 meters.
