Dielektrikum presents new ATSC 3.zero SFN antenna collection on the NAB Present

RAYMOND, Maine—Dielectric announced today that it will be showcasing its NextGen TV Powerlite TFU-WB-LP series at the NAB Show 2021 October 10-13 at the Las Vegas Convention Center, which will feature an extensive sample portfolio and coverage optimization for Single Frequency Networks (SFN .) offers) and LPTV applications.

The new antenna system series, announced in 2020, is designed with NextGen TV in mind and features a range of elevation gains, azimuth patterns with high front and back ratios, and software tools to help broadcasters develop and deploy ATSC 3.0 SFNs, the company said.

Dielectric’s Proposal Generator software will help broadcasters configure SFN systems to suit very specific network designs. For each SFN location, transmitters can select the right power level, directional pattern, height above ground, and other relevant design criteria.

“After extensive calculations and design changes, we brought our Repack product portfolio to market with ATSC 3.0 power requirements in mind, but optimized for high-performance transmissions,” said Keith Pelletier, Vice President and General Manager of Dielectric.

“The SFN has more to offer than just being robust enough to carry the ATSC 3.0 signal. They require an even bit distribution from two or more transmission locations throughout the broadcasting market. That means providing antennas with exceptional accuracy to ensure that coverage gaps between transmission sites are properly closed and signal strength in the market is increased evenly, ”he said.

Dielectric developed the series while working with consultants on theoretical SFN deployment plans. Customers specifically requested products designed for an SFN business model, the company said.

The new Powerlite TFU-WB-LP series offers antennas, transmission lines, tunable filters and RF components in one all-inclusive package. They are built in four-bay steps with a maximum ERP of 100 kW for each antenna. They are also available with higher performance options, the company said.

The new series is adaptable to multifrequency networks and can serve both narrowband and broadband RF configurations. The series can also work with more traditional high-power high-tower antennas that many broadcasters want to keep operating, Dielectric said.

The NAB Show 2021 will take place October 10-13 at the Las Vegas Convention Center. See dielectric at NAB booth C7215.
