TV broadcasters have a lot on their minds this year at the NAB Show in Las Vegas. New efficiencies enabled by IP video transport as well as IT technology and next-gen TV made possible by ATSC 3.0 are near top of mind. But no issue facing over-the-air TV broadcasters at this year’s gathering tops the FCC-mandated repack of the television spectrum.

Tests conducted in Cleveland this summer revealed that ATSC 3.0 can support multiple simultaneous services modes, such as high-data-rate HD and 4K, and highly robust signals for mobile delivery. Wayne Luplow of Zenith R&D Labs recently presented the findings at the IEEE Broadcast Symposium and submitted them to the FCC.

This summer, Phil Kurz, TVNewsCheck’s technology editor, hit the road to visit the manufacturing facilities of Dielectric, Electronics Research Inc. (ERI) and GatesAir (above) to see how each is preparing for the expected spike in demand for antennas, transmitters and other RF components as a result of the TV spectrum repack. This is what he learned.
