I have some questions concerning antennas like the fan dipole, cobweb or hex beam which consist of separate wire antennas for each band. For this discussion we'll say it covers 10, 12, 15, 17 and 20 meters. Since no manual switching between the individual antennas takes place, when the radio is set to say, 20 meters: 1. Is it receiving signals from all five of the antennas? If so, is that a benefit or a hindrance? 2. Does it transmit through all five at once as well? If so, is the amount of power going out on 20 meters only 1/5 of the total power transmitted?
