  2. 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.

  3. Monopole antenna - Wikipedia

    en.wikipedia.org/wiki/Monopole_antenna

    Common types of monopole antenna are the whip, rubber ducky, umbrella, inverted-L and T-antenna, inverted-F, folded unipole antenna, mast radiator, and ground plane antennas. The monopole is usually used as a resonant antenna; the rod functions as an open resonator for radio waves, oscillating with standing waves of voltage and current along ...

  4. Isolated ground - Wikipedia

    en.wikipedia.org/wiki/Isolated_ground

    The primary reason for the use of isolated grounds (IG) is to provide a noise-free ground return, separate from the equipment grounding (EG) return. The EG circuit includes all of the metal conduit, outlet boxes, and metal enclosures that contain the wiring and must be grounded to provide a safe return path in case of fault currents.

  5. Counterpoise (ground system) - Wikipedia

    en.wikipedia.org/wiki/Counterpoise_(ground_system)

    Counterpoises are typically used in antenna systems for radio transmitters where a good earth ground connection cannot be constructed.. Monopole antennas used at low frequencies, below 3 MHz, such as the mast radiator antennas used for AM broadcasting, require the radio transmitter to be electrically connected to the Earth under the antenna; this is called a ground (or earth).

  6. Mast radiator - Wikipedia

    en.wikipedia.org/wiki/Mast_radiator

    The ground also serves as a ground plane to reflect the radio waves. The antenna is fed power between the bottom of the mast and ground so it requires a grounding (Earthing) system under the antenna to make contact with the soil to collect the return current. One side of the feedline from the helix house is attached to the mast, and the other ...

  7. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    It is difficult to design a single antenna to receive such a wide wavelength range, and there is an octave gap from 216 to 470 MHz between the VHF and UHF frequencies. So traditionally, separate antennas (outdoor antennas with separate sets of elements on a single support boom) have been used to receive the VHF and UHF channels. [6]

  8. Ground plane - Wikipedia

    en.wikipedia.org/wiki/Ground_plane

    For a monopole antenna (a), the Earth acts as a ground plane to reflect radio waves directed downwards, making them seem to come from a virtual "image antenna" (b).In Telecommunications, a ground plane is a flat or nearly flat horizontal conducting surface that serves as part of an antenna, to reflect the radio waves from the other antenna elements.

  9. Folded unipole antenna - Wikipedia

    en.wikipedia.org/wiki/Folded_unipole_antenna

    The folded unipole antenna is a type of monopole mast radiator antenna used as a transmitting antenna mainly in the medium wave band for AM radio broadcasting stations. It consists of a vertical metal rod or mast mounted over and connected at its base to a grounding system consisting of buried wires.
