Exploring the End-Fed Half Wave Antenna

Tony K6TTP sent us this article on the end-fed half-wave antenna written by John VA3KOT for Ham Radio Outside the Box. “This is probably the best overview article on end-fed half-wave antennas I’ve read in many many years. It broadly addresses in brief the fact and opinion that exists in the EFHW world, and explains the complexities, alternatives, and some variations on the type.” It’s a great introduction for anyone considering constructing one of their own. The caption for the image accompanying this post reads, “49:1 showing 2xFT140-43 ferrite cores. No case, insulated wire protects windings from moisture.”
