Leif, SM5BSZ http://www.sm5bsz.com/ has put on YOUTUBE 4 videos named Sensors- Parts1 to 4.
The addres of the first video (sensors – part1 ) is http://www.youtube.com/watch?v=ItLkn8r4s3E and the others can be find easily there.
“On low frequencies where antennas are small compared to the wavelength, the Electric and magnetic fields are separable. Interference sources are typically magnetic or electric and it helps to use E-field sensors and H-field sensors to understand how fields of one or the other kind propagate into the receiver.”
These videos are closely related to the small loop and small dipole antennas implemented in AAA-1 kit. The user will reach better undestanding of the electromagnetics behind the small antennas and will help him to install the antennas in proper way to reduce the man made noise from our noisy environment.
