Abstract
A center-fed VHF dipole antenna structure particularly adapted for 30-80MHz peration wherein one half of the radiating structure comprises the outer conductor of a coaxial feedline which includes a low-loss cable choke at the lower end of the half dipole length of the feedline while the other half of the dipole consists of a conventional radiating conductor element. Additionally, remotely controlled variable impedance elements are included at the feedpoint to provide selective coarse and fine tuning of antenna resonance.
