Default omnidirectional CTC spacing

Assume a circle of radius "r" with sources of equal amplitude spaced at equal intervals along its circumference. For a particular frequency (f) and distance (d), How close do the sources need to be in relation to each other to achieve an omnidirectional radiation pattern?

Hi thadman,

(r/2) dictates the highest possible omni frequency with WR drivers i.e. f <= 344/ ((2xr)/4) if all are connected in phase but if Bessel configured, omni is achieved for all frequencies.
