Ultra High Frequency (UHF): 300-3000 MHz This is currently the most commonly used frequency band.
Read moreWhat does 2m 70cm mean?
2m- Good all around band for talking/chatting , but since its VHF, signal travel depends on what’s in its way and the power output of the radio. 70cm- Good band, since its UHF its good to have in the city or around tall buildings or inside of buildings because its wavelength penetrates obstacles better.
Read moreWhat is high frequency range?
High frequency (HF) is the ITU-designated range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz . It is also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres).
Read moreWhat are the three frequency range?
Three doesn’t rely on just one frequency band for its mobile network. In fact, it uses quite a few of them, namely the 700MHz, 800MHz, 1400MHz, 1800MHz, 2100MHz, 3400MHz, and 3600-4000MHz frequencies.
Read moreWhat is the wavelength of the UHF band?
UHF, abbreviation of ultrahigh frequency, conventionally defined portion of the electromagnetic spectrum, encompassing radiations having a wavelength between 0.1 and 1 m and a frequency between 3,000 and 300 megahertz. UHF signals are used extensively in televison broadcasting.
Read moreWhat frequency is 70 cm?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
