These popular designs are still in common use and the ‘constant turn’ design originating in Australia have been universally adapted as standard FM receiving antennas for many factory produced motor vehicles as well as the existing basic style of aftermarket HF and VHF mobile helical. Another common use for broadside helixes is in the "rubber ducky antenna" found on most portable VHF and UHF radios using a steel or copper conductor as the radiating element and usually terminated to a BNC / TNC style or screw on connector for quick removal.
