We present results of a set of experiments to investigate the effect of a dissipative external electromagnetic environment on tunneling in linear arrays of junctions in the weak-tunneling regime. The influence of this resistance decreases as the number of junctions in the chain increases and ultimately becomes negligible. Further, there is a value of external impedance, typically ∼ 0.5 kΩ, at which the half-width of the zero-voltage dip in the conductance curve shows a maximum. Some new analytical formulae, based on the phase-correlation theory, along with numerical results will be presented.
