Art scoffs at Kraus and Art scoffs at experience with antenna
orientation for best reception. So that readers aren`t mislead, olease
refer to page one of Terman`s 1955 opus:

"---radio waves. travel with the velocity of light and consist of
magnetic and electric fields at right angles to each other and also at
right angles to the direction of travel." Then check page 923:

"--- E is the field strength of the wave in volts per meter, Psi is the
angle between the plane of polarization and the wire in which the
voltage is induced" ---It will be observed that the quantity E cos Psi
cos theta is the component of the field strength which has a wavefront
parallel to the antenna and is polarized in the same plane as the
antenna."

He who scoffs at Terman is at great peril.
