The band is used by international shortwave broadcasting stations (2.310 – 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services , among other uses.
Read moreWhat are the advantages of using high frequency signals in telecommunication systems?
Explanation: The main advantage of high frequency signals is that the signal may be transmitted over very long distances and thus dissipates very less power . The antenna height required for transmission is reduced at higher frequencies.

High-Frequency Characteristics Required of Relays
Read moreWhy do we use higher frequency?
Increasing the frequencies will give everyone more “room” to transmit radiowaves . Increasing data rates, because having a higher carrier frequency also allows to widen the communication channel. Miniaturization (higher frequencies = lower wavelengths = smaller antennas and systems)
Read moreWhat is low frequency used for?
The Low Frequency (LF) band is mostly used for AM broadcasting in Europe as well as in areas of Northern Africa and Asia . Similar to VLF, LF can also be used for navigational radio beacons. It can also be used for maritime ship-to-shore communication, as well as transoceanic air traffic control.
Read moreWhat is ultra high frequency 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 affects HF communication?
Space weather impacts radio communication in a number of ways. At frequencies in the 1 to 30 mega Hertz range (known as “High Frequency” or HF radio), the changes in ionospheric density and structure modify the transmission path and even block transmission of HF radio signals completely.
