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
thousands of phone patches to/from SE Asia on that rhombic and the 20m
monobander @ 90 feet. I used to break into QSOs between two local VKs
chatting via ground wave with that antenna. I was the only signal they
could hear.
You probably knew Mike Reason. When I was there, he was a local kid who
used to hang out at the MARS station. Great guy, now SK.

Can you expand on this, Ken, or if easier, a reference? I'm curious
what tradeoffs are made. I used a rhombic at Ft. Monmouth, NJ before
the Army base was closed in 2011, and used to boom into Europe and
Russia. It was amazing. I also got copies of WWII manuals on rhombic
construction while there. You know, just in case I became wealthy
with tens of acres of land. :-)

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.
