Refraction, diffraction and interference

The distance between adjacent intensity maxima can be increased by

decreasing the frequency of the microwave signal.

decreasing the distance $D$ between the transmitters and the receiver line.

increasing the separation $d$ of the two transmitters.

increasing the power of the microwave transmitters.
