A weather radar antenna for radiating a desired beam formed by feeding quadrants of the antenna uses a dual-mode switched aperture antenna feed. The dual-mode switched antenna feed has an input divider that splits the input signal. A left switch switches the split input signal using a left first diode and a left second diode to top left and bottom right quadrants of the antenna. A right switch switches the split input signal using a right first diode and a right second diode to top right and bottom left quadrants of the antenna. The diodes are forward and reverse biased as required to feed top, bottom, left and right portions of the antenna to obtain the desired beam. When all the diodes are reversed biased the split signal is fed to all quadrants of the antenna.
