Both approaches have significant problems:

The trap results in an inverted L that is only 25 high - very low
efficiency.  The loading coil (at high power) results in high
voltage across the insulator at the bottom of the "whip" which
is a weak point (and will melt down!).

Sounds like a great design! Thanks for your usual job of exposing the fundamental problems with poorly designed products.
