  2. Channel Master - Wikipedia

    en.wikipedia.org/wiki/Channel_Master

    In the 1980s, Channel Master was the only second source for General Instrument (GI)'s Videocipher II module, a building block for satellite television receivers, under a licensing agreement for which Avnet paid GI a million dollars. The Channel Master 4251, a high-performance parabolic UHF television antenna, stood about seven feet in diameter ...

  4. Antenna rotator - Wikipedia

    en.wikipedia.org/wiki/Antenna_rotator

    An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...

    2.4 GHz helical antenna radiation pattern (NEC simulation) The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling computer program for wire and surface antennas. It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly ...

  6. SMATV - Wikipedia

    en.wikipedia.org/wiki/SMATV

    The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω. To convert it to 75 Ω, a matching transformer (or balun) is used. For trunk line isolation, a resistive inductive device known as a splitter is used.

  7. Radiation pattern - Wikipedia

    en.wikipedia.org/wiki/Radiation_pattern

    In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source.

  8. Channel state information - Wikipedia

    en.wikipedia.org/wiki/Channel_state_information

    In wireless communications, channel state information (CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering , fading , and power decay with distance.
