Which is better UHF or VHF?

The question of whether UHF (Ultra High Frequency) or VHF (Very High Frequency) is better depends largely on the application. VHF bands are in the frequency range of 30 to 300 MHz and are often used for long-distance outdoor communications because the waves can travel further and penetrate better through obstacles such as trees or landscape features. UHF bands, on the other hand, which are in the 300 MHz to 3 GHz range, offer better performance in urban environments or densely built-up areas due to their higher frequencies, as they can more easily penetrate through solid objects such as buildings or even interiors such as walls. Additionally, UHF frequencies have more available channels, which can result in less interference. For applications where space traversal and penetration are important, such as in urban environments, UHF could be a better choice. For open areas or simple applications with fewer structures that could block the signal, VHF is often better suited.
