Cellular antenna adaptor cover

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.

Loaded antenna

A base loaded antenna is provided, which securely holds the inductive loading coil of the antenna while minimizing capacitive coupling of adjacent coil turns. A coil support has fins with grooves that hold the coil, so most of the space between adjacent coil turns contains only air. A cover surrounds the coil, and the coil support is loaded in tension while the cover is loaded in corresponding compression. A base on which the coil support and cover are mounted, is held to a vehicle sheet metal body by a star plate that lies on the underside of the sheet metal. The star plate has bent-up peripheral portions that 'dig' into the sheet metal to make an electrical ground connection therewith, and a flat middle for making electrical and mechanical connections to outer coaxial conductors.
