Actually, when I lived in Taiwan in the late 1960's, there was a religious
broadcasting station there that used a three-element tribander (modified
for BC frequencies, I assume) to broadcast to the mainland. The quad
parasitic array was, I believe, developed at broadcast station
HCJB. Today, VOA et al frequently make use of curtain arrays that,
depending on their configuration, can be very directional indeed. One of
the other things that is (or was) on the F12 web site was N6BT's
description of using a 21 dBi gain broadcast curtain in a DX contest.
