It became clear that at LF an active whip is a capacitance coupled to the
electric field. If it is accepted that a whip is a capacitance coupled to the
electric field, shape becomes irrelevant, as long as the required capacitance
is available. In practice the "whip" can be e.g. a small piece of copper
clad printed circuit board. A small die-cast aluminium box can also be used,
with the buffer amplifier mounted inside
