The Final All Band Antenna Solution

When last addressed, my approach was to use a three band trap dipole to cover 75, 40 and 30 meters and rely on the triband beam for 20,15 and 10 meters.

Since then I have discovered that trap dipoles exhibit reduced bandwidth. The bandwidth gets narrower and narrower as more bands are added. Therefore I have settled on two bands per dipole and two dipoles to cover 75, 40 and 30 meters.

One dipole takes care of 75 meters and the 40 meter CW band. The other dipole takes care of 30 meters and the 40 meter PHONE band.

Both dipoles are mounted as inverted-vees one below the other and at right angles to each other.
Seems to work fine. There is no real directionality. Each antenna appears to be omnidirectional on all bands.
