Dielectric, a privately owned company headquartered in the US, was founded in 1942 and employs approximately 140 individuals. The company reported $18.0M in revenue as of 2024. Functioning as a manufacturer of connectivity infrastructure, Dielectric produces television and FM broadcast antennas, transmission lines, and RF systems. The company provides television and radio broadcasters with antenna and signal-transmission systems designed for low- and high-power users, serving both rural audiences and major metropolitan markets.
On May 1, 2026, Dielectric electrical engineer Mersedeh Najishabahang was recognized as one of TVNewsCheck’s Women to Watch during the Women in Technology Awards at the NAB Show. Previously, on April 27, Dielectric announced its support for low-power television (LPTV) expansion across the U.S., with Lowcountry 34 Media's Jeffrey Winemiller selecting Dielectric antennas and RF systems for large-scale LPTV deployments. Earlier, at the NAB Show on April 26, the company unveiled an expansion of its OptiLoad series, introducing a new external heat exchanger system. This solution aims to improve thermal management, reduce noise, and lower HVAC requirements by relocating heat generated by RF loads outside of transmitter buildings. This follows news from April 17 that Dielectric is supporting a new era of LPTV expansion, driven by the FCC’s first major LPTV rule modifications in over 40 years, which aim to create opportunities for broadcasters to relocate facilities, resolve interference, 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.
