Abstract
An antenna with a loading coil ( ), is constructed with the spacing between turns of the coil and the diameter of the coil being precisely fixed in a mass-produced loading coil. Three rib members ( ) are provided that have slots ( ) that receive the turns of the coil, with the rib members being circumferentially spaced about about the axis ( ) of the coil. The lower ends ( ) of the rib members are fixed in radial position to the bottom ( ) of the loading coil frame ( ), and the upper ends ( ) of the rib members are connected to a ring ( ) that braces the tops of the rib member to each other and that expands the diameter of the upper portion of the coil, to form a rigid combination of coil and rib members.
