ABSTRACT:
This invention is a lightweight, portable, quickly assembled, wide band, discone antenna for high frequency ground wave communication. The disk portion of the antenna is formed of telescoping spokes and the cone portion is formed of separate retractable wire elements. Disassembled, the antenna can be carried in a backpack. It can be assembled in less than ten minutes to achieve non-fading, non-line-of-sight communication.
