The Antenna System
original source1)
We use Magnetic (H-Field) antennas or Electrical (E-Field) antennas or both. H-field antennas can be sub-divided into loop antennas and ferrite rod antennas.
See also Antennas for System BLUE (Some practical examples).
One or more antennas
Your receiver works fine with either H-Field or E-Field antenna.
Both types have their advantages and disadvantages.
You can easily start with one of them, and then install the other later, or settle for one.
