Abstract
The method is for mounting aerial dipoles in the form of two quarter wave elements, such that static charges are continually leaked away. The design avoids the use of a leak resistor and consequent loss effects in the H.F. band. The two dipole elements (1-2) may be held rigidly in various configurations. In the simplest case the element (3) into which the dipole ends are push fitted and from which the coaxial cable connections are made via contact screws (7-8) is formed from some metal loaded plastic, providing a finite resistance in the one to 10 kilohm range. The dipole assembly is held in a mounting (4) of some insulating material.
