Radio masts and towers - Wikipedia

Radio masts and towers are, typically, tall structures designed to support antennas for telecommunications and broadcasting, including television.There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them.Shortwave bands - WikipediaShortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper MF band and all of the HF band). They are the primary medium for applications such as maritime communications, international broadcasting and worldwide amateur radio activity because they take advantage of ionospheric skip propagation to send data around the world.3.5 to 30 MHz Automatic Antenna Impedance Two-way communications using 3 MHz to 30 MHz, high-frequency (HF) radio, also known as shortwave radio, offers worldwide coverage with no required infrastructure between stations, making it useful for emergency communications. Worldwide range is possible due to HF radio wave refraction in the ionosphere known as skywave propagation.
