Many stations are forced by terrain to rely on Single Frequency Networks (SFN) to augment station coverage. While simple in concept, the real-world design, installation and operation can be a challenge. In this two-part series, broadcast engineer, Ned Soseman, offers an examination of his experience with multiple SFN transmitters, which provide coverage to key populations spread through the hilly Ozark Mountain’s terrain. If you have, or are planning to install SFN transmitters, his experience may prove invaluable. Read on.
As broadcast and production professionals look forward to NAB 2018, thoughts center on expected new technology. What will be some key products and technology, what about new workflows, what surprises may greet attendees?

Is broadcast TV ready for hyper-local transmission?
Interest in TV SFNs is growing because ATSC 3.0 is designed to leverage the technology for maximum bandwidth, and Pearl and Sinclair scouting the trail to a new way of broadcasting. SFNs aren’t new. Springfield MO Fox affiliate KRBK has been operating a multi-transmitter ATSC 1.0 SFN for several years. How is 3.0 going to be different?
Learn if SFN might be a solution to your station’s delivery challenge in the article, “Pros and Cons of a TV SFN in US Market 75: Part 1.”
The KRBK SFN transmitter site, 5 miles north of Halfway MO, is the one tower the station owns. The satellite dish is the STL.
In part 2 of this series, broadcast engineer Ned Soseman reviews key differences in underlying ATSC 1.0 versus 3.0 technology and the effect that may have on SFN placement. He notes that while reliability of SFN transmitters is crucial, some SFN sites can be more crucial than others, such as the ones that cover areas where the most viewers and sponsors are located. Soseman reviews important keys to maintaining a reliable SFN, especially in today’s repack and ATSC 3.0 world.
