![]() 2 eyehooks with washers and nuts (I used #8 diameter, but size is up to you.) One is for the top of the box so that it can be hung up.One PVC DWV Test Cap (available at big box hardware stores in plumbing).4 x 4 x 2 electrical junction box (available at big box hardware stores).The short piece is for the “primary winding” of the transformer, and the long piece is for the “secondary winding” of the transformer. Two pieces of 14 gauge enameled wire (e.g., Thermalese), one short piece (about 1 foot in length) and one long piece (about 7 feet in length).I included the tools I used to analyze the transformer as well this is only necessary if you are interested in analyzing your project. ![]() Please note that I will not be describing the construction of the antenna wire radiator here. ![]() You will also need a half-wavelength length of wire (14 or 12 gauge typically) in order to construct an antenna radiator for whichever ham band you choose. The following is a list of materials required to make a 49:1 unun impedance transformer for an end-fed half wave antenna.
