Examples
Campbell was tasked with continuing the investigation into Stone's bimetallic cable, but soon abandoned it in favour of the loading coil.
Enormous antenna loading coil used in a powerful longwave radiotelegraphy transmitter in New Jersey in 1912.
The masts are inductively lengthened and fed by a loading coil (see: electrical lengthening ).
Since an antenna which had been too short now appears as if it were resonant, the addition of the loading coil is sometimes referred to as "electrically lengthening" the antenna.
So to make an electrically short antenna resonant, an inductor called a loading coil is inserted in series with the antenna.
The loading coil is usually inserted at the base of the antenna, between it and the transmission line (base loading), but sometimes it is inserted in the center of the antenna element itself (center loading).
