In the late '50s I was stationed at a field station in Northern Germany
that was monitoring transmissions from the 'other side'. We were at a
former WWII German airfield and had an antenna farm comprised of
rhombics. I never bothered to count how many there were but I estimate
that there were
Mike: You will need more than "a few tens of acres" for rhombics, their
beamwidth is so narrow that you will need an array of them. The

probably at least a square mile, likely more. Rhombics for the

Well, I'm not wealthy. But we do have 270 acres of forest-land covered
with nothing but trees. So a rhombic or two sounds really good, which

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.
Either way, half your power goes the "wrong" way, either behind your

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
The K3S is an incredibly compact and extremely capable rig. It has a handle on

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
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.

All ...
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.)
As I often say …
Good idea. A fellow ham I worked with once had a rhombic favoring the south
pole many decades ago. He was a significant communications option for an
expedition down there. It was a unique ham radio experience.

A 50 ohm dummy load. There's never any noise, never any QRM, the
frequency is always clear, and always a 1:1 SWR. Of course getting a

when I turned on the K3S tonight I noticed that the current display was
jumping between 1,4 and 2,7 Amperes on idle. Never saw the rig doing it
before. The actual current consumption didn´t change but the readout of the
