Dielectric To Showcase FM And TV Products

Dielectric has spent the past several years strategically building out its radio and TV product line to prepare for what the company forecast as its strongest business opportunities following the TV repack.

At NAB Show 2025 (Booth W3000), Dielectric will highlight how its recent technology innovations have prepared them for business growth in FM radio — and for the future of NextGen TV as broadcasters inch closer to planning ATSC 3.0 single-frequency networks (SFNs).

Dielectric will be showcasing FM and TV products developed for modern RF systems, which is similar to their recent work in the scientific community using RF technology to address global energy needs. The scientific applications use passive RF components similar to a broadcast transmission infrastructure, including amplifiers, transmission line, components and antennas — with some key differences. Dielectric engineers utilized many decades of broadcast design excellence to advance the company’s RF innovations for the scientific community. The broadcast depth drove efficiency and performance improvements in the scientific space, and in the future these scientific opportunities may similarly yield efficiency and new designs for the broadcaster.

"Our RF design innovations are adaptable to the broadcast and scientific markets. We’ve been able to capitalize on those fundamental design affinities by offering similar yet unique design solutions for both markets," said Keith Pelletier, President, Dielectric. "For example, high-power UHF television systems typically require coaxial transmission lines between four and eight inches in diameter," said Keith Pelletier, President, Dielectric. "In comparison, we are producing 12-inch coax for energy plants, using similar techniques to efficiently manage and dissipate the heat that is produced as signals move through the transmission lines. The similarities between the broadcast and scientific designs are beneficial to both markets."

On the FM side, Dielectric will accentuate how its recent product development strategy and business partnerships has led to brisk business. The company recently started shipping its DCR-E antenna, adding a seventh model to its DCR family of ring-style antennas. Dielectric’s DCR antennas offer broadcasters a lightweight yet robust structure with low windload, increasing long term reliability, simplifying maintenance, and reducing stress on tower structures. Dielectric will also preview a new ring-style antenna to be formally introduced in June that will be the first in a new series of products.

In addition to FM system replacement, Dielectric’s reconfigurable manifold combiners have opened more doors to the master antenna market. Dielectric’s expandable manifold architecture has generated interest from master antenna owners in large markets and metropolitan centres that expect to add new tenants over time. New tenants are added quickly and easily by plugging a filter into an open port and adding transmission line. The design accelerates new station launches without increasing the RF footprint. Dielectric recently won a new FM master antenna project through its partnership with SCMS.
