www.arrl.org40-meter dipole fed with 80-meter energy has a low radiation resistance but very high reactance. In either case, the antenna current (and therefore the radiation) is very small. The current applied to the feed point of a multiband dipole takes the path of least impedance, automatically se- lecting the proper-length radiator. A Four-band Novice ...
