VHF radio waves have longer wavelengths than UHF, giving them better propagation across open spaces with minimal signal loss from reflection. This makes VHF the preferred frequency choice for golf courses, outdoor construction sites, marinas, open festival grounds, and other environments where teams operate primarily in open air with minimal building obstruction. VHF signals travel farther in line-of-sight conditions but penetrate building materials — concrete, steel, energy-efficient glass — significantly less effectively than UHF. For operations that span both indoor and outdoor areas, repeater systems or UHF-based deployments are typically required to maintain full coverage.
