Earths, losses and vertical antennas (http://www.robkalmeijer.nl/technek/electronica/radiotechniek/hambleden/radcom/1992/10/page35/index.html). Please click link to read the full article and to view examples of Bobtail Curtain antennas. Author: Rob Kalmeijer. Rob Kalmeijer has assembled an easily understood tutorial on the design, construction, and use of Bobtail Curtain Antennas. Bobtail Curtain Antennas are excellent low-angle vertical radiators exhibiting a broadside, bidirectional pattern. These antennas offer modest gain and some directivity. Most Bobtail Curtain arrays are used for single band use, but can be adapted to other bands with a sturdy antenna transmatch (i.e. "tuner"). HF Bobtail Curtains use a lot of space especially for frequencies of 7 MHz and below. A 10 meter Bobtail Curtain Antenna is certainly manageable and can be used to good advantage when the band is open. The illustrations accompanying the tutorial will give you a general idea of the di
