1. A communications device comprising:
a radio frequency (RF) device; and
an antenna coupled to the RF device and comprising
a conductive ground plane,
a conductive support rod carried by the conductive ground plane and extending outwardly therefrom, and
a conductive body coupled to and surrounding the conductive support rod, the conductive body extending from the conductive support rod to define an outer radial edge, the conductive body having a helical slot extending from the conductive support rod to the outer radial edge of the conductive body and to define a helical slot radiating antenna, the conductive body having a proximal end defining a first gap with adjacent portions of the conductive ground plane; and
a first coaxial cable coupling the RF device and the antenna, the first 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 the proximal end of the conductive body.
