Small-loop antennas for MW AM BCB. LF and VLF reception (2):

Last month we examined the basic theory of loop antennas, and demonstrated some of the basic forms of loop antenna, resonating methods and coupling methods. In this second and final installment we will take a look at the actual construction of practical loop antennas, some representative loop preamplifier circuits, and a couple of interesting, if odd, applications of loop antennas.
