Sigmatek Banner
Since its formation, Sigma Tek has continued to manufacture and distribute aviation instruments, accessories and control panels to the worldwide aviation industry. We are continuously conducting research and development for improvement of our current product line as well as for the development of new products.

In 1990 Sigma Tek decided to delve into the development and marketing of new state-of-the-art digital radio/audio control panels for the commercial aviation market. Since then Sigma Tek has made many breakthroughs in the advancement of technology. Our plans are to continue on in this age old tradition.
Even though Sigma Tek is a small company, we are a major force in the general aviation community. In our brief history we have managed to grow and be profitable throughout the dedication and hard work of our employees. This performance was during a period in which general aviation was suffering one of the worst downturns of any industry in our nation's history.
We are proud of our heritage and hope that you will help us to continue to grow and prosper in the years ahead. As we begin in the new millennium, we are enthusiastic about our prospects.
