My favorite SOTA antenna is the End-Fed Half Wave Antenna. There are many good descriptions on the net about this type of antenna. I recommend a good reading on this subject by Steve Yates, AA5TB at: www.aa5tb.com/efha.html. However, let me write about it from a slightly different perspective that was not very obvious from the articles I read. This article will describe a 40/30/20m band end-fed half wave antenna, focusing on its matching unit. It will present its parameters, so anybody with basic home-brew skills will be able to build it. Nevertheless, I will also describe, how it is designed, if one decides to embark on building it for different bands.
