====================================

Cecil, get yourself up to date.

A terminated rhombic is only 50 percent (or even less) efficient.

Actually, that is not true.

A big enough rhombic is nearly self-terminating. The energy radiated
is not available to the terminating resistor and thus is not -lost-.

It transmitts to, and receives from, only half of the available
directions. A wicked waste of power. I can't imagine why anybody
bothers to use one which is not rotateable.

Have you ever erected a 160-meter or 80-meter or even a 40-meter
rotateable rhombic? smiley

I completed my 2-meter Worked All Continents award by working VK5MC,
who was using stacked rhombics (350 feet/leg), partially steerable by
a rope and pulley arrangement. Worked for me [g].
