1. A communications device comprising:
a radio frequency (RF) device;
an antenna comprising
a conductive ground plane,
an elongate support extending from the conductive ground plane, and
a helically wound conductive strip carried by the elongate support, the helically wound conductive strip having a helical blade shape defining an auger shape in combination with the elongate support; and
a coaxial cable coupling the RF device and the antenna, the coaxial cable comprising an inner conductor and an outer conductor surrounding the inner conductor, the outer conductor coupled to the conductive ground plane and the inner conductor extending through the conductive ground plane and coupled to a proximal end of the helically wound conductive strip.
