Here's a basic, effective, and efficient antenna transmatch ("tuner") for feeding random length wires, especially half-wave, end-fed wires. Stan Gibilisco (W1GV) explains the design, construction, and use of this simple device. If you don't feel like building your own random wire tuner, you can buy a MFJ-971 Travel Tuner, which incorporates most of the features Stan describes. I have one of these tuners and it works well for portable or emergency operations. If you have trouble loading this video, please enter the title link into your browser: https://youtu.be/6QwBiz_LB9M.
