There is a monopole antenna with length of 141m.

So the antenna operates in 531kHz frequency. (lambda=c/freq, length of monopole antenna = lambda/4)

Let's say that I wrapped the antenna and make a N turns loop antenna.

(the loop antenna should operates in 531kHz too)

Then, are these equations right?

R is radius of the loop.
