  2. Werner Co. - Wikipedia

    en.wikipedia.org/wiki/Werner_Co.

    Werner reported audited net sales of $472.3 million for the year ending Dec. 31, 2005. As of March 31, 2006, Werner reported assets of $201 million and liabilities of $473.4 million. [ 3 ] Werner Co. filed for Chapter 11 protection under the bankruptcy code in Delaware on June 12, 2006, primarily due to excessive leverage, significant increases ...

  3. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...

  4. G5RV antenna - Wikipedia

    en.wikipedia.org/wiki/G5RV_antenna

    With no matching unit, Varney specified 75 Ω cable be used at the junction of the ladder line and coax (not 50 Ω); the higher 75 Ω impedance makes a closer match the end of the ladder line. An earth-grounded 4:1 voltage balun may be used to connect the coax to the ladder line, and 1:1 current balun should be used between the coax and the ...

  5. Conformal antenna - Wikipedia

    en.wikipedia.org/wiki/Conformal_antenna

    In a conventional phased array the individual antenna elements are mounted on a flat surface. In a conformal antenna, they are mounted on a curved surface, and the phase shifters also compensate for the different phase shifts caused by the varying path lengths of the radio waves due to the location of the individual antennas on the curved surface.

  6. 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.

  7. Monopole antenna - Wikipedia

    en.wikipedia.org/wiki/Monopole_antenna

    The antenna is resonant at this length, so its input impedance is purely resistive. The input impedance has capacitive reactance below ⁠ 1 / 4 ⁠ λ and inductive reactance from ⁠ 1 / 4 ⁠ to ⁠ 1 / 2 ⁠ λ. The gains given in this section are only achieved if the antenna is mounted over a perfectly conducting infinite ground plane ...

  8. Antenna feed - Wikipedia

    en.wikipedia.org/wiki/Antenna_feed

    The antenna feed system or antenna feed is the cable or conductor, and other associated equipment, which connects the transmitter or receiver with the antenna and makes the two devices compatible. [ 1 ] [ 2 ] In a radio transmitter, the transmitter generates an alternating current of radio frequency , and the feed system feeds the current to ...

  9. Guy-wire - Wikipedia

    en.wikipedia.org/wiki/Guy-wire

    A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires.. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure.
