This statement facinates me:
related by someone in Saudi Arabia
who
wrapped 1.2 kM of wire around a piece of PVC and vastly improved their
reception of WWV in the states.
1.2 kM of wire; Heck of a lot of capture area !
Very little capture area if it's all coiled up in a small space.
Is there some ratio of loop diameter and spacing between the wire loops that
results in the most capture area?
The bigger the diameter, the bigger the capture area.
There is a nice ratio of mirror diameter to magnification limits in telescopes
This is the analogy I was thinking of.
Yes, but what you'd be concerned with here is 'light gathering power'
(aka aperture), not magnification.
