A multi-turns magnetic-loop for the top band
Magnetic-loop that I am using for the 160m band, wich provides the best rejection of the white band noise generated by the 380kV power line, passing some 200m

Magnetic loop antenna new theory
The loops shown are all coupled with a ferrite transformer which is used to match the 50 ohms coaxial feeder to the feed point resistance of the loop
Loop Magnetic
Diameter 1.27 meters. Perimeter 4 meters. Width 80 mm. Material Dural alu.Loop antenna with manual tuning. Motor drive is planned
Magnetic Loop Antenna
Although a magnetic loop antenna aka small loop antenna is very compact, its efficiency is close to a half-wavelength dipole if carefully built
