Dielectric is setting a new benchmark for FM radio innovation with its RingMaster Series of high-efficiency antenna systems. First announced last year at Dielectric’s Radiovana event, the next-generation antenna series will be making its worldwide public debut at NAB Show 2026 in Las Vegas. Dielectric will demonstrate technological simulations and share real-world success stories of RingMaster deployments in the US and Bahamas at booth C1446.
By merging the proven performance of Dielectric’s DCR Series with a groundbreaking new architecture, RingMaster offers a more economical, efficient and adaptable solution for side-mounted FM systems. The series includes five models, each engineered with a streamlined design that uses up to 33 per cent fewer components than traditional configurations due to its reduced radiating elements.
Integrating both full and half-wavelength spaced arrays, RingMaster allows broadcasters to achieve full FM bandwidth performance – something previously associated with half-wave spacing only. Dielectric’s new approach means operators can maximise spectral performance while significantly reducing antenna weight and potentially costs. Its lightweight construction addresses critical system challenges, such as tower loading, structural concerns and installation complexities.
The flexible design also introduces controlled elevation pattern shaping, providing customers with flexibility and improved signal uniformity across the coverage area. Through its advanced design, RingMaster reflects Dielectric’s core objectives: reducing costs, extending longevity and enhancing revenue potential for broadcasters.
“The RingMaster Series sets a new benchmark for the future of FM antenna systems,” says Keith Pelletier, President of Dielectric. “By combining decades of engineering expertise with innovative design thinking, we have created a solution that empowers broadcasters to deliver higher-performance transmissions with greater operational efficiency.”
RingMaster antennas are already live and operational across the United States and beyond, with deployments extending as far as the Bahamas. A notable installation was completed for Bonneville International, where the RingMaster antenna supports a major infrastructure upgrade, accommodating thirteen FM radio stations broadcasting from Farnsworth Peak, Utah.
In Cedar Hill, Texas, private owner and operator of communications infrastructure, Vertical Bridge, installed a RingMaster auxiliary system to transmit FM and HD Radio signals for ten stations serving the Dallas-Fort Worth market. In these and numerous upcoming installations, RingMaster is demonstrating its value as a more economical, efficient and adaptable side-mounted FM antenna solution.
“NAB Show 2026 will mark the first public showcase of the RingMaster Series,” adds Pelletier. “It’s an opportunity to showcase Dielectric’s latest innovations to the people RingMaster is designed to support.”
NAB Show 2026 will be held at the Las Vegas Convention Center from April 19-22.
