Abstract: A whip antenna is constructed in three sections which screw together end-to-end to form the complete antenna. Each section comprises a flexible fibreglass rod which is surrounded by a sleeve of braided copper wire over a major part of its length, this sleeve serving to pass radio frequency current along the section during use of the antenna. One or more of the sections includes a capacitor or series connected capacitors connected in the radio frequency path along the antenna. Utilizing the fibreglass rod as a dielectric the capacitor electrodes are formed either by copper tape or conducting paint lying on the surface of the rod, the electrodes being digitally or helically intermeshed. Alternatively the electrodes may be formed as metallic rings surrounding the fibreglass rod and a conducting rod within the fibreglass rod.
