Q46. What is the polarity of the currents that feed the V antenna?
RHOMBIC ANTENNA
The highest development of the long-wire antenna is the RHOMBIC ANTENNA (see figure 4-37). It
consists of four conductors joined to form a rhombus, or diamond shape. The antenna is placed end to end
and terminated by a noninductive resistor to produce a uni-directional pattern. A rhombic antenna can be
made of two obtuse-angle V antennas that are placed side by side, erected in a horizontal plane, and
terminated so the antenna is nonresonant and unidirectional.
