The propagation pattern from a dipole forms a toroid centered on the
middle of the dipole wire. Radiatiation is perpendicular too the center
of the wire. There are nulls at the ends of the wire.

Adding a wire or wires between enda of the simple dipole does nothong to
change its radiation resistance, antenna efficiency, directional
pattern, or directive gain. Drivepoint impedance increases with added
wires as total antenna current is divided among them. If two equal wires
are used in the folded dipole, its drivepoint impedance is four times
the impedance of the single wire dipole. If there are three wires, the
impedance is multiplied by nine. Impedance varies by the square of the
number of same sized wires in the folded dipole.
