Esta antena tiene irradiante de 613 mm y geometría esférica. El diseño ha evolucionado desde la primera versión, que solamente tenía 4 meridianos, hasta la versión de este documento, con 4 meridianos, ecuador y bobina espiral. Aunque es parte de un experimento, realmente sirve para operar en VHF. El diámetro de la esfera es 52 mm.

This antenna has a 613 mm radiant and spherical geometry. The design has evolved from the first version, which only had 4 meridians, to the version in this document, with 4 meridians, equator and spiral coil. Although it is part of an experiment, it really serves to operate on VHF. The diameter of the sphere is 52 mm. Whoever wishes to achieve SWR=1 on the entire band can add a 104 mm diameter sheet metal circle, which advantageously replaces the radfials. In my case, the circle has a 15 mm hole in the center, to be able to clamp it between the male PL259 connector and the female PL259 of the downstream coaxial, when I use the fixed antenna at home. The circle is well trapped between both connectors and well connected to ground.
