Abstract: A door seal is provided to be used in the construction of a door for a shielded enclosure to assure that high and low frequency elecromagnetic fields do not penetrate the shielded enclosure. The “voltage dividing door seal” of U.S. Pat. No. 4,677,231 is improved by reconfiguring the seal to allow the addition of one or more spring finger rows. This provides a lower impedance seal and less voltage drop across the seal at lower frequencies and consequently, better shielding effectiveness.
