What type of radio signal is most likely to be affected by physical obstructions?

UHF signals, which stand for Ultra High Frequency signals, are typically more affected by physical obstructions than other types of radio signals. These signals operate at higher frequencies, ranging from 300 MHz to 3 GHz. As the frequency increases, the wavelength decreases, which makes UHF signals more susceptible to degradation when encountering obstacles such as buildings, hills, and other physical barriers. In contrast, VHF signals (Very High Frequency), AM signals (Amplitude Modulation), and FM signals (Frequency Modulation) generally have longer wavelengths and therefore can diffract around obstacles or propagate more effectively over larger distances. This means that while all radio signals can be affected by obstructions to some degree, UHF signals exhibit a more pronounced sensitivity to these physical barriers due to their high frequency.
