Then there's the small stuff that tells you a lot about the person behind the product: both antennas ship with ground stakes on paracord, packed in their own little pouch, ready to go. It's a tiny detail, but it's exactly the kind of thing that separates a well-thought-out kit from a bag of parts.

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

Whether you own an antenna analyser or just the SWR meter built into your rig Well done — you've purchased your EFHW from www.radio-stuff.com. This is a comprehensive guide to tuning it. An End-Fed Half-Wave (EFHW) is one of the most rewarding antennas an amateur can put up. One wire, one feedpoint, one coax run, and five bands. But it only delivers on that promise if the wire is the right electrical length, and "the right length" is never quite what the calculator told you.

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

Before I move ahead with this blog post I want to just do a little background comment on why I have written it. Over numerous years there have been lots of blogs, videos and commentary about how good or bad EFHW antennas are. Lots of advice, some good, some bad and some ugly, on how to set them up. Also, we see whole bunch of marketing nonsense related to power and no Tune no ATU stuff. So, before I rabbit on, I just wanted to say at Radio-Stuff.com we do spend a lot of ti
