Dielectric, a privately owned company headquartered in the US, was founded in 1942. The company employs approximately 140 individuals and reported $18.0M in revenue as of 2024. Specializing in connectivity infrastructure, Dielectric manufactures television and FM broadcast antennas, transmission lines, and RF systems. The company equips television and radio broadcasters with antenna and signal-transmission systems designed to meet the needs of low- and high-power users serving both rural audiences and major metropolitan markets.
Dielectric electrical engineer Mersedeh Najishabahang was recognized as one of TVNewsCheck’s Women to Watch during the Women in Technology Awards held at the NAB Show 2026 on April 21, celebrating emerging talent and innovation in media and entertainment technology. Previously, on April 27, Dielectric supported a new era of low-power television (LPTV) expansion as Lowcountry 34 Media's Jeffrey Winemiller selected its antennas and RF systems for large-scale LPTV deployments across the U.S. On April 26, Dielectric expanded its OptiLoad series at NAB, unveiling a new external heat exchanger system designed to move heat generated by RF loads outside transmitter buildings, which aims to improve thermal management, reduce noise, and lower HVAC requirements. This followed the company's announcement on April 17 regarding its support for LPTV expansion, prompted by the FCC’s first major LPTV rule modifications in more than 40 years, which create opportunities for broadcasters to relocate facilities, resolve interference conflicts, and expand service coverage.
Dielectric's customers primarily consist of connectivity and distribution services and broadcast television and radio companies. Examples of Dielectric's customers include Television Jamaica and BAI Communications.
