US 2013/0342406 A1 · HF ANTENNA ASSEMBLY

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.

Dependent claims

An antenna assembly for providing high frequency (HF) radio communication in two different operating modes, said antenna assembly comprising:

a whip antenna, operative for establishing short range HF radio communication with a communication target, via ground wave or low efficiency skywave propagation, allowing communication when said antenna assembly is in motion;
and
at least two antenna wire segments, deployable to form an inverted-V antenna using said whip antenna as a center mast, said inverted-V antenna operative to establish short or medium range HF radio communication with a communication target, via Near Vertical Incidence Skywave (NVIS) or directional skywave propagation, allowing rapid deployment of said antenna wire segments when said antenna assembly is stationary.
