Abstract
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.
