The cone can not radiate in phase with the rest of the antenna, their currents are inverted and hence canceled. The Vector 4000 can not display absolutely free space gain over a dipole.* The SIRIUS VECTOR 4000 is a fed dipole at one end as a Zeppellin or J-pole antenna. For that reason they can not show a pattern of gain in a model. If you have a model, so I do it public as public do I design models. I've published several, you publish any we serve the amateur? As proof that it affirms? with words of cars salesman?
