AudioShockwav: The function of forum, comment, and discuss radios, antennas and technology. Users assigned to the antennas fantastic properties, are the ones to try. It is not my case, I deny these fanciful or commercial intent properties. In the case of V4000, the Dominator, all "tests" are empty words and drawings marketing. No single calculation made with EZNEC, 4NEC2, etc, giving to a V4000 or DOMINATOR a gain than a simple dipole. This is what has been proven in this thread, made by you, to whom I give my thanks really. Greetings Ernesto.
