There is a difference. The small whip has a high capacitive
reactance.
The small loop has a high inductive reacvtance. Both have low
radiation
resistance. But, the loop is more often used to determine EM field
strength. You just need the right "fudge factor" to convert antenna
voltage tto field strength or vice versa.

=====================================
For the very last time I will repeat my question :-
"What is the voltage measured between the bottom end of a 1 metre
vertical antenna and ground when the field strength is 1 volt per
metre.
The height (length) of the antenna is much less than 1/4-wavelength.
The bottom end of the antenna is immediately above the ground. The
ground is assumed perfect. The field is vertically polarised.
Frequency, loops, reactance, radiation resistance do not enter into
the argument. No other information is needed.
Terman, Kraus and Balanis' bibles provide answers to a different
question in which I am not interested. Mere mention of these learned
gentlemen only confuses the issue.
The answer is entirely fundamental to e.m. radiation and reception.
All I need is a number of volts. What is it please?
