The story of how the Cubical Quad antenna came into being is a fascinating one. It was created out of necessity following an emergency call for help from radio station HCJB back in the early 1940s. HCJB was located high on the mountains of Ecuador. Their new upgraded 10Kw transmitter was literally setting their antenna system on fire. As a result, this Christian radio station (in the words of W9LZX) "received divine intervention. This "intervention" heralded the birth of a new and unique antenna. It was given the title of "Cubical Quad," and the word spread quickly among the Ham Radio community. Was it a genuine antenna with amazing gain or simply a hoax?
