The problem is that many stations migrated from well propagating VHF to UHF with the digital migration. The higher frequency signal experiences more fade due to atmospheric conditions and ground clutter. They also jam multiple channels into the same bandwidth the single old channel used to occupy, further reducing EIRP per channel.
- fomine3 5y agoVHF -> UHF transition is same here in Japan. After digital TV transition, empty VHF frequencies considered to worth for something like broadcast service for mobile device, so the service(NOTTV) started. But the service is failed due to not attracting (and partially because iPhone don't support it), so now not utilized again. How VHF frequencies utilized in other countries?
