Does VHF or UHF have longer range?
UHF two-way radios have a range that is wider than VHF. This means that UHF frequencies have smaller waves that produce a greater range. They are more likely to pass barriers like rocks and trees easier. VHF range is reduced due to signal degradation with barriers such as trees or hills.
