I'm always looking for new antenna ideas, especially when the ARRL Field Day rolls around (23-24 June 2018). I discovered this fascinating article by John Huggins (KX4O) during a cursory glance through the https://www.dxzone.com website.
According to John, this post is a "discussion of (the) asymmetrical hatted-dipole antenna, a portable antenna that can be used for field day, sota, campings, or even for fixed installations..." John adds that the AHDA is a "free standing 20-10 meter antenna that is really easy to build...and easy to carry."
John takes you step-by-step through the design, building, and use process with an ample supply of photos, performance graphs, and actual field tests of this uncommon antenna.
John used parts from DX Engineering to build the basic antenna, including aluminum tubing, a resin support column, and miscellaneous items. A sturdy tripod speaker stand supported the antenna, while a homebrewed choke balun made from RG-316 coaxial cable and a Type 43 toroid finished the project. John said he spent around $250 for the entire project, which is suitable for both home and portable operations.
Even if you can't commit the time and money to build this antenna, the design contains some interesting features worth your attention.
