Ray of the "Radio Workshop" presents another outstanding video tutorial for radio amateurs. In this video, Ray shows us how to design and build an "aerial tuning unit" for end fed wires, including inverted L antennas. The project is a simple, effective, and inexpensive L match ATU which can be used for both Amateur Radio and the international shortwave broadcast bands. Ray's easy going style makes often complex theory understandable and doable, even for those of us with limited construction skills. This easily-made L match ATU can be used for both home and portable operations.
