Coaxial QFH antenna for VHF

A coaxial QHF (Quarter-Wave Helical Feed) antenna is a type of antenna designed for satellite radio communication. It typically consists of a helical structure wound around a cylindrical core, with one end connected to the center conductor of a coaxial cable. QHF antennas are often used in applications like satellite communication, NOAA Weather Satellite WX Signal reception and amateur radio.
