Rhombics definitely look cool, but modern antennas definitely outperform them
My favorites:
- four stacked rhombics, (two wide, two high) over a salt marsh in ZC4
this array was replaced by a curtain array, steerable in azimuth and elevation
- a rosette of sloping rhombics occupying one square mile. Sloping rhombics
broaden the elevation pattern, much like stacked Yagis.
- many pairs of very wide spaced rhombics used for diversity reception at VOA
Greenville Site C
As for 160 meters, I'll keep my 4-square transmitting array, Beverages and
phased arrays of short receiving verticals!

Tom,
Why? The same reason guys put up quads. They LOOK very cool! Imagine
standing on one end of the rhombic and saying "well, you can't see the end
of the antenna without the binoculars - but it's out that-way somewhere."

I can't imagine why anyone would have one today. Here is an analaysis of
Rhomics.
