We have pulled together some of the most answered questions about End Fed Half Wave antennas into this simple FAQ section. What is an EFHW antenna, and why does it need tuning? An End-Fed Half-Wave is a single wire cut to half a wavelength on your lowest band and fed at one end through a matching transformer. Because it is a resonant wire rather than a tuner-fed random length, its length sets where it works. Tuning simply means adjusting that length until the SWR minimum sits where you want...

Before we charge into the build, let's reflect on the Moxon. The Moxon antenna, originally developed by Les Moxon (G6XN), is a two-element, rectangular-shaped directional antenna that provides high performance in a compact and mechanically simple configuration. Functionally, it is a folded variant of the two-element Yagi–Uda antenna, in which the tips of the driven and reflector elements are bent toward each other, forming a rectangle. This geometric modification reduces the overall boom...
