Terrestrial antennas are devices designed to receive and transmit radio signals over land. They are commonly used in communication systems, such as television and radio broadcasting, to connect with ground-based stations. These antennas can vary in size and shape, depending on their specific purpose and the frequency of the signals they handle. These antennas operate by converting electrical signals into electromagnetic waves and vice versa. They are essential for enabling wireless communication, allowing devices like smartphones and television sets to access content without the need for physical connections. Terrestrial antennas play a crucial role in modern communication infrastructure.
