Abstract
A system particularly useful for feeding antennas employing one electrical wavelength closed loop driven elements. Single or dual wire transmission line sections provide impedance match between the high voltage, high impedance feed point on the loop and a low impedance antenna feed line. Selectable polarization with high isolation between feed lines is provided by the connection of a second transmission line section to a point located 90 electrical degrees away on the loop, at the current maximum when the other feed point is excited.
