Understanding the Broadcast Spectrum The broadcast spectrum is a finite public resource, carefully managed by government agencies to prevent interference between different users. While your television guide might display channel 7, the physical broadcast frequency could be located anywhere in the UHF band.
Solving UHF Signal Reception Problems and Optimization
Importantly, the transition also involved a significant reallocation of spectrum, known as the broadcast incentive auction. The physical characteristics of these frequencies mean that VHF waves travel farther but are more susceptible to interference from structures, whereas UHF signals offer better quality and capacity but generally have a shorter range.
This decoupling means that an antenna must be tuned to the specific RF frequency, even though the viewer thinks they are watching channel 4. Channel Numbers and Virtual Channels Following the digital transition, the concept of a "channel" became more abstract.

VHF operates in two bands, low-VHF (channels 2-6) and high-VHF (channels 7-13), while UHF covers the higher channels, ranging from 14 to 36. UHF: Technical Differences The technical divergence between VHF and UHF frequencies dictates their real-world performance.
