STLs, or small transmitting loops. Also known as magnetic loop antennas. Diminutive in size, but big on performance!
Loading coils add inductance to the antenna system, allowing for a shorter radiator. Also permits the use of several bands without the need for a tuner.
Impedance transformers for end fed wire antennas, both resonant and non-resonant.
