22 de feb. de 2021 · I segnali ad altissima frequenza (VHF) vengono trasmessi da 47 a 230 megahertz (MHz), mentre l’ultra alta frequenza (UHF), come suggerisce il nome, arriva molto più in alto, da 470 a 862 MHz. Una frequenza più alta in MHz significa proprio quello che sembra, ovvero che le onde sono più frequenti. I loro picchi e avvallamenti si propagano ...

La principal diferencia entre UHF y VHF es el rango. La radio bidireccional UHF tiene un alcance mayor que el VHF. Esto significa que las frecuencias UHF tienen ondas más pequeñas que producen un rango más amplio. Los obstáculos como rocas y árboles son más fáciles de superar. Debido a la atenuación de la señal de obstáculos (como ...
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
