Artificial RF Ground
Maximize your antenna's efficiency.
The ideal RF ground is having your station equipment mounted in and thoroughly grounded to a metal tub floating in salt water. Hani stations in boats approach this ideal, but the rest of us usually have to settle for considerably less efficient RF grounds. The many hams living in high-rise apartments and condos, even those with their stations on the ground floor of the typical house, have station ground leads many feet long between the equipment and actual ground-While this provides the DC ground necessary for safety, it is seldom an efficient RF ground on all the bands that you normally work.
