A 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 …

zA 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)

a 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

California who made excellent receive only Magnetic Loop antennas with filters to block out powerful AM And FM stations. Using some nice YouTube videos from the SDRUNO crowd, I was able to configure my next generation SDR receiver to the Mag Loop and experience the mystery and joy of configuring WSJT-X, after some more YouTube of course.

What 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.
