Custom RF Products & Design

In addition to products for the Commercial sector and the Amateur Radio community, Kessler Engineering is able to satisfy requests for special niche products and applications. One such example of the ingenuity that we can provide is the patented Kessler-Coates (KeCo) tactical antenna switch (see above).

The KeCo switch was invented to solve a very specific problem encountered by US military forces and has been widely fielded within the US DoD ever since. Because of the novel ideas demonstrated and perfected by the KeCo design, the USAF immediately recognized the innovation that it represented and a patent was subsequently awarded to the two inventors, Don Kessler and David Coates.

About Don Kessler, Owner: Don Kessler grew up in central California and while in junior high, began working in a radio & television repair shop. After high school, he attended the United States Air Force Academy and graduated in 1982 with a Bachelor's degree in Electrical Engineering and a commission as a Second Lieutenant in the USAF. He spent the first half of his military career as a fighter pilot flying the A-10 (the greatest fixed-wing tactical aircraft!).

He was later stationed at Wright-Patterson Air Force Base, where he attended Wright State University in Dayton, Ohio, ultimately receiving his Masters' and Doctorate degrees in Electrical Engineering. He possesses a wide breadth and depth of knowledge and experience gleaned from working varied engineering programs and projects while on active-duty, as a defense contractor, and in the commercial sector. His hobbies include electronics, Amateur radio, and restoring early radio sets from the 1920's.
