  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.

  4. Radio masts and towers - Wikipedia

    en.wikipedia.org/wiki/Radio_masts_and_towers

    A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.

  5. Owens Valley Radio Observatory - Wikipedia

    en.wikipedia.org/wiki/Owens_Valley_Radio_Observatory

    It consists of 288 dipole antennas spread out over a desert area equivalent to about 450 football fields. [6] The OVRO-LWA produces whole-sky radio images in the 30 to 88 megahertz band. [7] The Deep Synoptic Array (DSA) is an array of 10 4.5 m (15 ft) parabolic radio telescopes currently used to detect and locate Fast Radio Bursts (FRB)s. [8] [9]

    en.wikipedia.org/wiki/List_of_Marconi_wireless...

    A double antenna tuning inductor house near the summit of Cefn Du and to the rear of the 1914 antenna, served to tune the antenna and earth screens of what were now two parts of a whole antenna, fed at the western transmitter building. The extension also had inductors at the far end, such that each part of the antenna had inductors at its ends.

    The operation moved to Oceanside, California, where, at one point, more than 400 radios per month were being manufactured, and some estimates say that more than 80,000 transceivers were sold during the company's lifetime. [1] [2] Swan merged with Cubic Corporation in 1967, and Johnson managed Swan as its subsidiary until 1973.

  8. Choke ring antenna - Wikipedia

    en.wikipedia.org/wiki/Choke_ring_antenna

    A choke ring antenna is a directional antenna designed for reception of GNSS signals from satellites. It consists of a number of concentric conductive cylinders around a central antenna. The first choke ring antennas were invented at JPL; [2] since 1989 they have been improved and extended by many companies. [citation needed]

  9. Antenna diversity - Wikipedia

    en.wikipedia.org/wiki/Antenna_diversity

    Antenna diversity is especially effective at mitigating these multipath situations. This is because multiple antennas offer a receiver several observations of the same signal. Each antenna will experience a different interference environment. Thus, if one antenna is experiencing a deep fade, it is likely that another has a sufficient signal ...
