Very nice. Note that the geometry of the antenna is defined by an angle. This is a characteristic of many types of broadband antennas, and is also interestingly present in the definition of scale- and angle-invariant object models used for image parsing in machine vision
This creates a strange and perhaps very deep connection between radio wave detection in the electromagnetic domain and object detection in the pixel domain.

Very appealing to the casual technically oriented observer.
I wanted to be an ARRL participant even when I was a kid back in the '40s, but things did not work out for it.
Love to have another 50 years to study these things out, but now too old and slow to easily grasp the theory and practice.
Kudos to those who do have the desire and ability! The kind of thinking we need.
Thanks for taking time to post this note, tbw2. Keep on!
