  2. Random wire antenna - Wikipedia

    en.wikipedia.org/wiki/Random_wire_antenna

    Often random wire antennas are also (inaccurately) referred to as long-wire antennas.There is no accepted minimum size, but actual long-wire antennas must be greater than at least a quarter-wavelength (⁠ 1 / 4 ⁠ λ) or perhaps greater than a half (⁠ 1 / 2 ⁠ λ) at the frequency the long wire antenna is used for, and even a half-wave may only be considered "long-ish" rather than "truly ...

    en.wikipedia.org/wiki/Transmitter_station

    They all have masts or towers to install antenna systems. In most cases, the mast is a passive structure to support the antennas. But in low frequency stations (such as AM radio), the mast itself may be the active antenna element. In such cases, the mast is isolated from the ground.(See Monopole antenna). If the mast itself is an active antenna ...

  4. Grounding kit - Wikipedia

    en.wikipedia.org/wiki/Grounding_kit

    Grounding kits for different diameters Part of a tin-plated ripple. Grounding kits / Earthing kits are composed of two main components, a clamp and a cable. The clamp will be screwed on a coaxial cable and in case of lightning strokes in the antenna installation, the voltage will be diverted over a ripple in the clamp with the combined cable and will be earthed / grounded by this way.

  5. Fixed wireless - Wikipedia

    en.wikipedia.org/wiki/Fixed_wireless

    Fixed wireless services typically use a directional radio antenna on each end of the signal (e.g., on each building). These antennas are generally larger than those seen in Wi-Fi setups and are designed for outdoor use. Several types of radio antennas are available that accommodate various weather conditions, signal distances and bandwidths.

  6. Distributed antenna system - Wikipedia

    en.wikipedia.org/wiki/Distributed_antenna_system

    The RF node with three antennas was at the platform and another antenna near the stairs on the far side. A distributed antenna system ( DAS ) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure.

  7. Broadcast transmitter - Wikipedia

    en.wikipedia.org/wiki/Broadcast_transmitter

    A broadcast transmitter is an electronic device which radiates radio waves modulated with information content intended to be received by the general public. Examples are a radio broadcasting transmitter which transmits audio (sound) to broadcast radio receivers (radios) owned by the public, or a television transmitter, which transmits moving images to television receivers (televisions).
