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.
