Vertical antennas are a type of radio antenna that stands upright, resembling a pole. They are commonly used for transmitting and receiving radio signals in various applications, including amateur radio and commercial broadcasting. Vertical antennas are often favored for their compact size and ability to cover a wide range of frequencies. These antennas work by radiating electromagnetic waves vertically, which can help improve signal propagation, especially over long distances. Vertical antennas can be simple designs, like a single vertical element, or more complex configurations, such as ground-mounted or multi-band setups, depending on the specific communication needs.
