One has to be careful in distinguishing between small loop vs.
Electrostatically shielded ("magnetic") small loop antennas.
Small loop is typically less than 1/4 wave single loop made of tubing (low
resistance - losses) and with efficient matching network.
The shielded small loop is variation of small loop antennas using electrostatic
shield (tubing with gap - opening)

Above referenced sites seem to use the name Magnetic Loop for wrong antennas
(just simple loop).

Got that Reg, Tom, Dick and Harry?
