Coil-shortened dipole antenna calculator (http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=32516). Author:  J.J. Johnson Accessed on 18 February 2017, 19:50 hrs, UTC. Please click link or insert title URL into your browser search box to read the full article. Comment: Here's another useful tool for antenna experimenters. With the suggestions given in this article, you can design, build, and use an effective dipole antenna that needs much less space than a full-sized dipole by adding two simple, inexpensive loading coils. The article provides a simple set of formulas to help you through the design and building process.  The author also supplies a simple coil inductance calculator and a link to a related article by Jerry Hall (K1PLP) in the September 1974 issue of "QST".
