Effective length and input impedance of the NIST standard dipoles

Computed values for the effective length and input impedance for a set of standard dipoles used at the National Institute of Standards and Technology are presented. These dipoles are used as calculable reference antennas in the calibration of dipole-like electromagnetic interference antennas in an open-area test site. Estimates for the uncertainty in the computed values of the effective length and antenna impedance are also given.
