I don't follow the logic of this at all. Are you expecting the trap
to cut off all frequencies above 27.5 MHz?

This is what W8JI's site hints at. Is he wrong, or am I misunderstanding
him?

Unlike low pass filters, traps do not have a low impedance
at lower frequencies and a higher impedance at high frequencies.
The impedance plot Vs frequency is akin to a bell shaped
curve with the maximum impedance at resonance.
