On a Bugcatcher coil, isn't this is what is happening? The coil is
usually tuned after the antenna is installed ? The Bugcatcher coil is
acting ilke a trap ?

A trap is operated at its resonant frequency. A bugcatcher
coil is supposed to be operated far below its self-resonant
frequency. So the bugcatcher is a lower impedance than a
trap and doesn't impede the current as much as a trap.

A trap operated at 1/2 its resonant frequency is primarily
inductive, like a bugcatcher coil.
