Title:
HF ANTENNA ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2013/035093
Kind Code:
A8
Abstract:
Antenna assembly for providing HF radio communication in two different operating modes. The antenna assembly includes a whip antenna and at least two antenna wire segments. The whip antenna establishes short range HF radio communication with a communication target, via ground wave or low-efficiency skywave propagation, allowing communication when the antenna assembly is in motion. The antenna wire segments are deployable to form an inverted-V antenna using the whip antenna as a center mast. The inverted-V antenna establishes short or medium range HF radio communication with a communication target, via NVIS or directional skywave propagation, allowing rapid deployment of the antenna wire segments when the antenna assembly is stationary. The antenna assembly may be mounted aboard a mobile platform, such as a vehicle.
