Thank you very
much for the replies Martin. I found your write up to be quite
excellent and informative. Thank you for providing a link to it.
I have read it twice and noted several questions and wondered if I
may send you a PM regarding them plus some comments regarding
several possible omissions (and one tiny typo)?

Hi Gedas,
?
At VLF it makes less of a difference, as the inductive
reactance is such a small proportion of the loop impedance.
?
At mid-frequencies the value of inductance starts to become
significant.
?
Taking a 1m diameter loop
?
5mm diameter (thin) conductor the inductance is around 3.38uH
25mm diameter (typical) conductor the inductance is around
2.37uH
75mm diameter (very fat) conductor the inductance is around
1.68uH
?
At mid-frequencies, around 10MHz, I'd expect to see about 3dB
improvement between 5mm to 25mm and another 3dB between 25mm to
75mm
?
These are some notes I made a while ago. I may be wrong, but
nobody seemed to be that interested in challenging what I
wrote.?
