===== Either Ferrite Antennas or Loop Antennas =====

H-field antennas can be sub-divided into [[en:hardware:antennas:h-field:loop|loop antennas]] and [[en:hardware:antennas:h-field:ferrite-rod|ferrite rod antennas]].

Magnetic has no need to be placed high since the magnetic field is not easily attenuated.
They must be minimum some meter from other electrical installations - In the garden just above the ground is ok, or attic, or balcony.
