Business and Organization

Tel-Instrument Electronics Corp. (“Tel” or the “Company”) has been in business since 1947.  The Company is a leading designer and manufacturer of avionics test and measurement instruments for the global, commercial air transport, general aviation, and government/military defense markets.  Tel provides instruments to test, measure, calibrate, and repair a wide range of airborne navigation and communication equipment.  The Company sells its equipment in both domestic and international markets. Tel continues to develop new products in anticipation of customers’ needs and to maintain its strong market position.  Its development of multi-function testers has made it easier for customers to perform ramp tests with less operator training, fewer test sets, and lower product support costs.  The Company has become a major manufacturer and supplier of Identification Friend or Foe (“IFF”) flight line test equipment over the last few years.
