DIY Magnetic Loop Antenna - Conejo Valley Amateur Radio …
www.cvarc.orgA magnetic loop antenna may be the answer and they are not as difficult to build as you might think. Like getting on the air for the first time or taking your license exam there is a certain amount of uncertainty when you first approach magnetic loop antennas, there are …
Portable Magnetic Loop Antennas - FARS
www.fars.k6ya.orgzA magnetic loop behaves electrically as a coil (inductor) with a small but non-negligible radiation resistance due to its finite size. It can be analyzed as coupling directly to the magnetic field (opposite to the principle of a Hertzian dipole which couples directly to the electric field)

www.philipstorr.id.aua lot of noise on especially the lower Ham bands. At my QTH reception on the low ham bands and especially AM on Medium Wave is dramatic. As a result I need reception antennas which are less susceptible to these noises. Loop antennas (magnetic) are known to accomplish this. So I build this simple active receive loop antenna to see if they work and

MAGNETIC LOOP ANTENNAS - Milford Amateur Radio Club
w8mrc.comWhat is a magnetic loop? • Radio waves travel by a wave of electric and magnetic fields at 90 degrees to each other. • Our regular antennas work by "recieving" the electric field portion of the radio wave. A small current is transduced on the antenna and the reciever amplifies it and converts it to audio.
