No, no. That's the LIRPA, from that QST article "Power a-plenty - for
pennies!" You just take the fat wire out of the back of your transmitter,
and connect it to a skinny wire, and at the joint, all the electrons
crowd together trying to get through the skinny wire, causing a dramatic
increase in voltage, much like a traffic jam.
That's called a stub. It's an impedance mismatch causing a standing wave.
The skin effect renders the thin wire resistive, so it's presence is not
relevant. This is a perfectly normal phenomenon, there is nothing silly
about it.

Well, notwithstanding the extraneous apostrophe, the whole thing was a gag.
Its name, LIRPA, is "April" spelled backwards, a la "April Fools!"
(to be fair, they didn't say just "Lirpa," they said "Lirpa 1".) :-)
