NAB. Dielectric has spent the past few years developing its radio and television product line to prepare for what the company sees as its strongest business opportunities following the television restructuring.
At the NAB Show 2025 (booth W3000), Dielectric will highlight how its recent technological innovations have prepared it for business growth in FM radio and for the future of next-generation television, as broadcasters approach ATSC 3.0 single-frequency network (SFN) planning.
Dielectric will showcase FM and television products developed for modern RF systems, which is similar to its recent work in the scientific community using RF technology to address global energy needs. Scientific applications use passive RF components similar to a broadcast broadcast broadcast infrastructure, including amplifiers, transmission lines, components, and antennas, with a few key differences.
Dielectric engineers used many decades of broadcast design excellence to promote the company's RF innovations to the scientific community. Transmission depth drove efficiency and performance improvements in the scientific space, and in the future, these scientific opportunities may lead to efficiency and new designs for broadcasting.
"Our RF design innovations are tailored to the broadcast and scientific markets. We have been able to capitalize on those fundamental design affinities by offering similar but unique design solutions for both markets," said Keith Pelletier, president of Dielectric.
On the FM side, Dielectric will accentuate how its recent product development strategy and commercial partnerships have led to a dynamic business. The company recently began 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 wind load, increasing long-term reliability, simplifying maintenance, and reducing stress on tower structures. Dielectric will also introduce a new ring-type antenna that will be formally unveiled in June and will be the first in a new series of products.
In addition to the replacement of the FM system, Dielectric's reconfigurable collector combiners have opened more doors to the master antenna market. Dielectric's expandable collector architecture has generated interest from master antenna owners in large markets and metropolitan centers who hope to add new tenants over time. New tenants are added quickly and easily by connecting a filter to an open port and adding a transmission line.
The design accelerates the launch of new stations without increasing the RF footprint. Dielectric recently won a new FM master antenna project through its partnership with SCMS.
Dielectric will also demonstrate its reconfigurable collector combiners for TV master antenna systems, along with its full range of broadband antennas for ATSC 1.0 and 3.0 systems. The latter includes a low- to medium-power antenna designed to serve SFN market configurations.
