This is post 2095 in a continuing series of articles on simple ham radio antennas. Thanks to Steve Ellington for this easy-to-understand tutorial on how to design and build a 49:1 transformer for End-Fed-Half-Wave antennas.  Steve does an excellent job of explaining both the theory and practical application of this useful device. Here are some of Steve's remarks: "Here is how I assembled a 49:1 impedance ratio transformer for my EFHW.

Thanks to Steve Ellington for this excellent tutorial on how to design, build, test, and use a 49:1 transformer for End Fed Half Wave Antennas (EFHW). Although EFHW antennas are fairly simple and inexpensive, they do require a transformer to match the nominal 50 ohm impedance of your HF transceiver to the often high impedance (2500 ohm plus) of half wavelength wire antennas. In addition to helpful construction details, Steve also shows us how to mount the matching device.  According to Steve, the toroid part number is 5952003801.  You can find these toroids here:  http://www.fair-rite.com/products/toroids.  You can find the enclosure at Lowe's.
