In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz ), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz).
Read moreWhat is the frequency band for the satellite communication and radar?
Use in satellite communication Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks .
Read moreWhich frequency band Cannot be used in satellite communication?
Which of the following bands cannot be used for satellite communication? Explanation: MF is a lower frequency band than Ku, C and X bands and does not lie in the microwave spectrum. Microwaves are used for satellite communication since the lower bands get reflected by the ionosphere. 8.
Read moreWhat is meant by RF frequency?
RF Frequency is a electromagnetic wave using AC (Alternating Current) . Just as the name implies, “frequency”, its something that happens over and over and over again. It is very frequent, consistent, and repetitive. There are different types of frequency; light, sound and in our case radio frequency (RF).

UK Business VHF Radios use frequencies from 136 – 174MHz . “Marine band” VHF radios used on ships and to communicate between vessels and harbours, bridges, locks etc, use frequencies between 156 – 162MHz. Specific channels are used for particular purposes, including for emergencies, ship-to-shore communications etc.

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).
