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?

Hi Nate,

Simply examine the transfer characteristics of any series or parallel,
resonant circuit. It has a peak, not a band-reject characteristic,
that is why it is called resonant. You resonate traps at one distinct
frequency where the roll-off may serve the purpose over a slightly
wider region. A 10M trap does not "remove" the surplus wire for all
frequencies above, say, 28.4 MHz, and probably doesn't work for the FM
portion of the band.
