Actually, it’s highly probable that Dickson has touched your life many times this year, even if we’ve never formally been introduced. Some of the prescriptions in your medicine cabinet were likely formulated and stored in precisely controlled environmental conditions monitored by Dickson data loggers or chart recorders. Some of the foods on your table, in your cupboard, or refrigerator were likely processed or stored at temperatures mandated by government regulations and monitored by Dickson instruments. You’ve perhaps walked through one or more of the thousands of public buildings – hospitals, libraries, stores and shopping centers, airports, museums, etc.—where Dickson data loggers and chart recorders ensure HVAC systems are optimized for human comfort and energy efficiency. The vaccines your children were immunized with were stored in precise conditions that were probably monitored by Dickson vaccine storage data loggers or vaccine storage chart recorders. Countless products that you use – from appliances, to autos, to airplanes and more—were engineered with the aid of Dickson instrumentation for capturing critical data on temperature or humidity conditions or other electronic signals. The utilities that serve you—for water quality, for gas lines—may have used Dickson pressure monitoring instruments to keep systems properly functioning. Every day, hundreds of calls come to the Dickson Customer Service phone lines from individuals across the globe seeking data loggers and chart recorders to help them capture the critical temperature, humidity, pressure, or electronic signal data that they need. Hundreds of more inquiries come in daily through the Internet. We keep a close ear to what each application needs, and the type of instrument features that each application requires. Wherever data is critical, Dickson technology provides a best-fit solution for application and regulatory requirements. We know that the data logger or chart recorder that is the best fit for one user’s application may not work well for another, and we maintain the world’s widest selection of top-quality instruments to ensure you’ll never have to make do with a less than optimal instrument match to your application.

We lead the world in complete systems from the transmitter to the tower top including towers, filters, combiners, switches and patch panels. Our service and installation capabilities complete the package. Our 125,000 square foot facility is located in the rural community of Raymond, Maine, about 45 minutes west of Portland, in the southern part of the state. Raymond is the home to Sebago Lake (second largest lake in Maine) and the landlocked salmon. We have the best of both worlds here in Raymond. Our close proximity to Portland allows us to take advantage of its urban offerings- more great restaurants than any other small city, a world class Symphony, and local sports the Portland Pirates hockey team and the Portland Sea Dogs baseball team. Our rural side affords us the opportunity to experience the magnificent lakes and mountains of this region of Maine and to view moose, deer, turkeys and other wildlife. We value our employees as our greatest resource. We are fortunate to be located in a state whose work force demonstrates a superior work ethic. Dielectric has a number of workers that have been with the company over 30 years and we experience a very low turnover rate. We are able to recruit high caliber talent from around the country based not only our reputation in our field, but also on the quality of life experienced here in Maine. Dielectric began in 1942, and in 1959 moved to our current facility overlooking Panther Pond. The Raymond plant has grown with the business over the years and currently covers 125,000 square feet. In 1998 we built an 18,000 square foot addition to support our growth in the DTV arena and to allow for increased manufacturing and antenna testing areas. This increase has led to improved processes, productivity and safety. In 1999 we added a 5,000 square foot addition that is the new home to our Engineering Offices and 1,000 square feet of additional antenna testing facilities. Our pressurization and sensor products divisions moved to Bridgton, Maine in 1999. This relocation added 45,000 square feet of manufacturing space dedicated to our dryer product line as well as freeing up space in Raymond for our expanded TV and FM businesses. In February of 2000 we acquired the television antenna division of Harris Corporation. 2001 brought continued growth to Dielectric. Early in the year we acquired both Central Tower and Ryan Construction of Newburgh, Indiana. The addition of these companies broadened our capabilities into the tower segment of the broadcast business. Our offerings now include custom tower manufacture, tower mapping, modification and a full line of tower related services. Central Tower is also well known in the wireless/PCS markets for their outstanding products and commitment to service. Later in 2001 we expanded further west and brought TCI of Fremont, California into the Dielectric family. TCI’s strength in the HF/MF fields and signal processing capabilities were a natural addition to the Dielectric offerings. Today Dielectric’s facilities span from coast to coast and encompass over 290,000 square feet of space. At Dielectric we are excited about the future of the broadcast industry as we venture into the digital era. We look forward to opportunities here and around the globe.

We are a manufacturer of High Q Multi-Layer capacitors (MLC) and Single-Layer capacitors (SLC), Resonators, Filters, Broadband DC blocks, Thin Film components, and Custom ceramic components. In 2004, DLI acquired Voltronics Corporation, a world leader in precision variable capacitors. Our primary manufacturing and product development facility in Cazenovia, New York , is equipped with modern equipment to assure consistent, high quality products that meet the growing needs of our markets. DLI supports its customers in virtually all geographic regions of the world. Our subsidiary, Dielectric Laboratories Asia Trading ( Shanghai ), provides sales engineering and logistics support to our customers in China . We manage an active global sales rep network from our regional sales offices in the USA, Europe, and Asia. The company was founded in 1974 in Fairfield, New Jersey as a manufacturer of high Q, temperature compensating multi-layer capacitors. We quickly realized that carefully crafted single-layer capacitors were superior to multi-layer devices for many higher frequency applications and this was the beginning of the DiCap® product line. It also spawned the basic philosophy that drives DLI today - deliver innovative products that enhance customers products. In 1977, the company moved to the current site. Dover Corporation purchased the company in 1985 and, today, DLI is an operating company within the Dover Electronics subsidiary.
