Nor is that the only form-factor you can use. I built this one inside large plastic food jars.  This is an active, regenerative FSL antenna built from 7 inch ferrite bars housed in large plastic food jars.  There is a pickup coil, a feedback coil, and a tuned coil. The pickup coil feeds an amplifier. The amplifier output goes through a 500 Ohm potentiometer to the feedback coil. This dramatically increases the sensitivity and narrows the selectivity - adjustable by the potentiometer.   The antenna also works as a regular FSL when the amplifier is switched off.
