Hi Yuri and others
We have a rhombic at the ZL6QH station, with 200m long legs elevated at about
20m above ground level. It is switchable between the short and long paths to
Northern Europe. Although the rhombic performs quite well, we have found that it
is generally not as effective as our yagi and long wire vee beams in contest
Rhombics exhibit high gain but the main lobe is very narrow. Our experience
suggests that antennas with more lobes and broader beams in the azimuth and
elevation planes are more useful for winning contests. I note that most
commercial rhombics were designed for point-to-point linking circuits, not
general coverage requirements
You can find more information about the ZL6QH station and antenna farm at
for Quartz Hill Management Committee

Very interesting and W6AM was certainly an icon and unique "hamonized"
commercial installation of rhombics.
Would you care and remember to share some anecdotes about Rhombics performance
vs. regular mortal's antenna installations?
I had Rhombic one summer, running FTDX400, and Kermadec expedition kept telling
me that I was only NA station that they were hearing when the band was "dead" to
I believe Rhombics are performing quite a bit better than what modeling software
would indicate (calculated gain vs. real life performance).
Tesla RC has acquired 175 salty - marshy acre Rhombic farm on NJ coast and we
are looking forward to resurect it, any advice and experiences are greatly
