consists of two horizontal half-wave antennas mounted at right angles to each other in the horizontal plane [10].

A line consisting of two insulated wires twisted together to form a flexible line without the use of spacers [10].

(2D)—Measures the range and bearing to a target [18].

(2M)—Miniature/microminiature repair program [14].

A parallel line consisting of two wires that are generally spaced from 2 to 6
inches apart by insulating spacers [10].

(TWIN LEAD)—A parallel two-wire line in which uniform spacing is assured by
two wires imbedded in a low-loss dielectric [10].
