Aha now I understand. Thanks for the info John.

Still no explanation what the "new Lahlum" metod is. Seems to be a modification to Lewallen but what is Lahlum? Is it a person or what is it???


The "new Lahlum" method is named after Robye Lahlum, W1MK.

Robye developed the mathematics for a very quick solution for
making a Lewallen type feed, but with NO limitations on the phase angles.

He also developed a testing method to allow the network to be
adjusted very easily.

The details will be out in ON4UN's upcoming book sometime this
coming spring.
