Good idea. A fellow ham I worked with once had a rhombic favoring the south

It might be enlightening to Google the G5RV antenna...
The design by Lou Varney, G5RV first appeared in the RSGB Bulletin
and was designed as a 20M -->ONLY<-- antenna, with a specific combination
of open wire and coax lengths. (I have a copy of the original article.)

Rhombic antennas derive their well-known gain by "throwing away" some of
the design's gain. Ditto for the infamous "inverted vee". Use is made of
the lobes from the four wires while disregarding others.

Hi Mike,
Rhombic antennas -- with few exceptions -- were not usually designed
for high gain. They were usually designed as a compromise between
gain and typically one octave of bandwidth (e.g. 14-28 MHz).
To compound the design compromises, the r hombic termination
resistor throws away nea
Maybe the termination was changed in later years. I was permanently
assigned to K2USA from '63-'65 (not bad duty for a ham). We ran

Mike: Rhombics can be operated either terminated or unterminated. If
unterminated, they are bi-directional with half the power in each lobe.
If terminated, the resistor absorbs half the power in the reverse lobe.

Many years ago W1AW used to have a big (6 wavelengths per leg as I
