As a small business founded in 1986, we started life as an EMC Consulting company.  After about 10 years of consultation, we decided to focus on and develop two major product lines that fall under the general "EMC Solution" umbrella.  

Coaxial RF Lightning and Surge Protector designs using Gas Discharge, Quarter-Wave, and Multistage technology. 

High Current EMI Feedthrough Filter solutions using C-Type (Capacitive) Filter technology.
