Abstract
An articulated element for an antenna such as a log-periodic dipole antenna having an elongated boom comprises an inner tubular section secured to the boom and an outer tubular section movable relative to the inner section between an extended or operative position colinear with the inner section to a folded or inoperative position transversely of the inner section. The element sections are interconnected by spring means which is always in tension and exerts a compressive force between the two sections for good electrical conductivity when in the operative position while permitting the outer section readily to be pivoted to the stowed position. A T-shaped sleeve secured to the inner section has slotted longitudinal and transverse legs which releasably clamp and provide strong mechanical support of the outer section in both positions.
