WebIt had always seemed logical to the writer that when ferrite rods first appeared in broadcast receivers. A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that is usually fed by a balanced source or feeding a balanced load. Within this physical description there are two (possibly three) distinct types: • Large loop antennas (or self-resonant loop antennas or full-wave loops) have a perimeter close to one or more whole wavelengths at the operating frequency, which makes them self-resonant a…
