What frequency range do UHF mobile radios operate between?

• A. 100 to 3000 MHz
• B. 300 to 3000 MHz
• C. 3 to 30 MHz
• D. 30 to 300 GHz

Answer: (B)

UHF stands for Ultra High Frequency, which spans from about 300 MHz to 3,000 MHz. This is the range used by mobile radios because it allows for compact antennas and good line-of-sight performance in urban environments. Frequencies below 300 MHz are considered VHF, while frequencies above 3 GHz move into microwave bands and are not typical for standard UHF mobile radios. Therefore, the operating range is 300 to 3000 MHz.
