Diamond shaped antenna identification

I think I know what antenna you're referring to, but for the life of me, I can't remember the name. Looks almost like an elongated hexagon with a loading coil in the middle. I'll keep digging.
I keep seeing the Isotron ISO 30 antenna when I look at that.
Is this what you are thinking of?

It's probably the most narrow-banded antenna you can use on HF frequencies. Reminds me of the 18-inch long center-loaded Hustler CB antenna of the 70s. Was commonly mounted on a rain-gutter clip. Remember rain gutters? That antenna would tune to a 1.3 or so at resonance on channel 12 and rise to 2.5 or 3 at channel 1 and 23.
The general rule is that the smaller the fraction of a wavelength your antenna size becomes, the more narrow-banded it will be.
The Isotron is no exception.

Isotron= The most expensive way to turn your coax into a con-mmon mode antenna.
Loaded my TS-530 into my White Lightning clone quad on 3675 one night. The radio's internal tuner helped. The 27 MHz series-fed driven element must have looked like about 5 ohms. Should put an analyzer on it one day just to see. The other folks on the sked that night heard me, but not all that well. Probably only because it was winter, no lightning crashes.
Probably a close approximation of the Isotron's 80-meter efficiency. Gotta figure I would have been 1 db below mental telepathy with summer lightning noise.
