A 75m bugcatcher coil is NOT a small inductor. It is a slow-
wave structure with a velocity factor of about 0.017, both
measured and calculated. That gives my bugcatcher coil an
electrical length at 4 MHz of about ~60 degrees.
Let's focus on one thing at a time.
You claim a bug cather coil has "an electrical length at 4MHz of ~60
degrees". That concept is easily proven false, just like the claim a
short loaded antenna is "90-degree resonant". Both can be shown to be
nonsense pictures of what is happening.
Assume I have a 30 degree long antenna. If the loading inductor is 60
electrical degrees long, I could move it anyplace in that antenna and
have a 90 degree long antenna.
We all know that won't happen, so what is it you are really trying to
say?
