The problem of many holes in a coaxial beam pipe is studied by means of the modified Bethe theory. The electromagnetic fields propagating in the coaxial region couple the equivalent dipole moments of the holes. The effect of the coupling on the longitudinal impedance and on the loss factor is investigated, showing that the interference phenomena are significant for such geometries
