The quad parasitic array was developed at broadcast station HCJB (by Jones)
when the tips of their Yaggi (made of 3" aluminum irrigation pipe) transmit
antenna melted off in the thin air of the over 10,000 feet elevation from
the 10 kW (AFAIR) transmitter. The Yaggi was aimed at the center of the US.
