A low-profile axial mode helical type antenna that employs hollow copper tubing for the radiating element, a singular semi hollow dielectric support structure, low pitch angle and an improved/simplified parallel open wire impedance matching technique. This antenna has a wide radiating pattern as well as high forward gain and circular polarization. It is designed to work in the field of live entertainment including reception and transmission of wireless microphones, in-ear monitors, communications and cue control systems. It operates from 470-663 MHz.
