In this post, Gil ("Radio Prepper") finishes his 49:1 Half-Wave End-Fed Antenna Transformer begun in our previous article (Post 2014, 07 October 2019). Now he field tests the device on a variety of amateur radio bands, including 6 meters and 30 meters.  The transformer performed well from 80 meters through 10 meters. Gil does an excellent job in combining theory and practice to produce a video that is clear, concise, and well-paced.

One of the drawbacks to end-fed and random length wire HF antennas is the high mismatch between the antenna (often more than 2000 ohms impedance) and your HF transceiver (normally, around 50 ohms impedance).  The resulting SWR will be enough to harm your rig. One way to reduce SWR and RFI concerns with these antennas is to use a 49:1 antenna transformer.  In this video from the "Radio Prepper", we get an excellent introduction to the theory, construction, and use of the 49:1 balun.  According to the "Radio Prepper", this transformer works well with wire lengths of 134 feet/40.85 meters and 67 feet/20.42 meters. Make one of these 49:1 transformers for your emergency "go kit" or for the next ARRL Field Day.  A simple, easy solution for matching your HF rig to end-fed half wave or random wire antennas.

This expertly presented video tutorial on random wire antennas was made by Terry Snyder (WB3KBN) at the November 2018 meeting of the Harrisburg Amateur Radio Club.  Terry does an excellent job of explaining the theory and practice of using random length wire antennas, paying particular emphasis on the wire lengths "not to use."  This video would make an excellent program for your Amateur Radio Club or for an amateur radio license class.

Thanks to "Tinker John" (W5CYF) for this simple, quick, and inexpensive way to bring your antenna coaxial feed line into your shack.  Although several companies sell similar devices (DX Engineering and MFJ), you may have more fun making your own pass-through panel, "Tinker John" does an excellent job of showing us how to make this practical and often necessary tool for your ham shack.

If you need a compact, simple, and inexpensive 2-element HF beam for your amateur radio station, then the "Moxon Antenna" or "Moxon Rectangle" is for you. The Moxon Antenna is a simple and mechanically robust two-element parasitic array antenna that exhibits modest gain and some directivity.  The antenna is named after it inventor Les Moxon (G6XN). In this video from HC1ZIX, we get an exceptionally clear discussion of the theory, design, and advantages of this easily-made antenna.  Why not build this antenna for your home or portable station?   You may be surprised just how well this basic "rectangle antenna" performs.
