ABSTRACT:
An antenna system is disclosed that can be extended from the base section of a notebook computer to position the antenna at a predetermined remote distance from electromagnetic interference power produced by the notebook computer. The antenna is rotatable and pivotable for multiple positioning relative to the blocking end of the antenna system that remains in the computer. Advantageously, the antenna system maximizes space by having a hollow blocking end coaxially received about a sleeve retaining the batteries used by the computer. Additionally, the antenna system includes a directional helix antenna rotatable at least 360.degree. by a stepper motor.
