Abstract
An integrated erectable antenna system comprises a mast pivotally mounted for rotation between a horizontal stowed position and a vertical operative position, and a log-periodic antenna assembly longitudinally slidably and pivotally mounted on the mast for movement between stowed and operative positions. The pivoted end of the mast has an extendible arm connected by cable to a hand operated winch. The antenna assembly comprises an elongated boom having many articulated transverse dipoles connected thereto over its length and foldable for stowing without disconnecting the dipole parts. The boom is hinged to the mast about one axis transverse to the latter for pivoting from a stowed position parallel to the mast to an operative position perpendicular to the mast and about another axis parallel to the boom for orienting the dipoles in either horizontal or vertical planes when the mast is in the vertical position. The entire system may be mounted on a standard size military passenger vehicle ("Jeep"), is collapsible into a space approximating the length and width of the vehicle, and is erectable to the fully operative position by one operator in less than five (5) minutes and by two op…
