Ease of Use Tuners on Market
LDG Company Overview
LDG has been a leader in the development of automatic antenna matching devices (tuners) for many years. As early as 1995, LDG Electronics pioneered the switched-coil automatic RF tuner. The tuner, controlled by a microprocessor, eliminates the need for manual tuning of capacitors and inductors, and the software automatically finds a match in seconds. Today, more than twenty-five years later, LDG has grown into an industry leader offering a wide range of tuners and other amateur products. By refining the original design with new tuning algorithms and improved components, LDG tuners define the state of the art.

Things to know about LDG Electronics
The first LDG tuner appeared as a build article in QST magazine (January 1996) and was available as a kit. The article and kit were very popular, and founder Dwayne Kincaid (WD8OYG) started LDG to build on the success of the design. LDG continues to be a family business, as Dwayne's son David is now also involved, bringing new skills and ideas to the table. In 2010, the company acquired S9Antennas to expand its product line. Today, LDG continues to bring new and exciting products to the amateur market from its labs in southern Maryland.
