The K6ARK Portable Radio QRP (5W max for high-duty cycle, 10W max SSB) matching unit design is one of the most compact and light-weight options for a portable HF antenna. This kit improves the original design, making the build easier. This kit provides the components necessary to build one matching unit. Just add antenna wire of your choice to build an End-fed Half Wave, End Fed Random Wire, or a 1:1 Balun feed point for a dipole antenna. Tools/consumables required include a soldering iron, solder, tweezers, and a heat gun (preferred) or a lighter to shrink the heat-shrink tubing. Note that this kit contains small parts that may be difficult for some individuals to assemble, but the end result is well worth it. These kits are produced by me, K6ARK, and I welcome questions, and am eager to help you succeed in your build project. Have fun with your build!
