Page 25: Low-Frequency Design Strategies
Low-Frequency Design Strategies While wave guides provide isolated control over various mid- to high-frequency coverage areas, the low-frequency section of a M’elodie array still requires mutual coupling — with equal amplitude and phase — to achieve better directionality. Low-frequency directionality is less dependent on the array’s relative splay angles and more dependent on the number of elements of the array. -
