The masts are inductively lengthened and fed by a loading coil (see: electrical lengthening ). Source: Internet
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. Source: Internet
So to make an electrically short antenna resonant, an inductor called a loading coil is inserted in series with the antenna. Source: Internet
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). Source: Internet
