Here's an interesting three-band HF antenna you can build with commonly available materials and a little creativity. According to AB8XX, this ground plane antenna covers the 20, 30, and 40 meter amateur radio bands, is omnidirectional, and offers a low angle of radiation. The feed point is approximately 20-ft./6.09-m above ground level. Also intriguing in this article is the homebrewed antenna launcher based on a design published in the March 2009 issue of "QST." The antenna spreaders are made from PVC pipe.
