ABSTRACT:
A top-loaded, helically-wound vertical antenna is described having an upright non-conductive core with a conductive element extending from a base upward alongside the core terminating in a closed, tightly-wound loading coil at the top of the core. The loading coil has a main upper coil segment and a lower small coil section which are separated a desired distance so that they are electromagnetically and electrically connected in series but sufficiently spaced to prevent temporary overloading. Electrically isolated booster coils are mounted about the conductive elements at desired locations of the lead section in which the booster coils are not electrically connected to the conductive element or to each other for boosting the reception of r-f energy.
