Impedance wise it's similar to the old flat tv ant wire more commonly know as 300 ohm twin lead.

The feeder is the twin lead going vertical. the horizontal portion are the elements cut to the wavelength or a fraction of the wavelength. A full length ant for the bcb is abt 300 meters (abt 900') long. This just element (horizontal portion).
In practicality 60-100 works well as high up as you can get it.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
