AN/URC-117 Ground Wave Emergency Network - Description

Description

GWEN transmitting antennas consist of a concrete foundation 2 feet (0.61 m) above grade, a 3-foot-high (0.91 m) insulator, a 290-foot (88 m) steel tower, and 4-foot (1.2 m) lightning rods enclosed by a 42-foot (13 m) × 47-foot (14 m), 8-foot-high (2.4 m) chain-link fence topped with barbed wire. The tower itself would be supported by 15 guy wires attached to the ground at six anchor locations. Surrounding the tower and attached to it at the top and anchored in the ground by concrete blocks would be 12 top-loading elements (TLEs). The purpose of the TLEs is to enhance the efficiency of the antenna. Anchors for the TLEs and guy wires would be within the site boundaries.

Famous quotes containing the word description:

    The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.
    Guy Debord (b. 1931)

    A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.
    John Locke (1632–1704)

    It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.
    Ludwig Wittgenstein (1889–1951)
