Dielectric to Showcase ATSC 3.0-Compatible Spectrum Repack Antennas
2018 NAB Show
ManufacturerDielectric will present an array of spectrum repack antennas engineered to deliver the enhanced performance required by the next-generation broadcast standard, ATSC 3.0. At the 2018 NAB Show, Dielectric will exhibit at Booth C2613 (April 9-12, Las Vegas Convention Center).
The broadcast industry is poised to start the transition from its broadcast-specific transport backbone to an IP-based transmission stream that can carry multiple 4K video programs, mobile and interactive services. At NAB, Dielectric will highlight the many features designed into their ATSC 3.0 compatible UHF/VHF repack antennas and components, including safety margins that withstand the higher peak to average power ratios of the new standard.
Dielectric is also preparing broadcasters for ATSC 3.0 with its FutureFill feature, which is included as standard in every center-fed, high-power repack antenna it manufacturers—at no extra charge. FutureFill increases power density by 7-to-9dB close to the tower, and reduces the main lobe gain by 1.2-to-1.4dB. The broadcaster can, if additional transmitter power is available, increase the TPO to overcome the main lobe gain reduction, or use Single Frequency Network technology to enhance reception at the periphery of the service area.
“FutureFill allows an existing ATSC 1.0 antenna to be adjusted so that its performance is boosted for ATSC 3.0, without having to be taken down from the tower or replaced,” said Jay Martin, vice president of sales, Dielectric. “With the transition from ATSC 1.0 to ATSC 3.0, we’re going to see greater focus on power density, higher vertical polarization ratios and polarization diversity, as well as the use of single frequency networks, all of which boost reception across the coverage area.”
