The shielding effectiveness of a pigtail connection between a coaxial transmission line and a ground plane is treated rigorously by the method of moments, as a function of the type and number of pigtails and frequency. The type of pigtail connection is shown to be crucial with regard to radiation and shielding effectiveness, even though the pigtail itself does not radiate significantly. A short pigtail is significantly better than a longer one. A 'sloppy' pigtail connection may actually enhance radiation. Multiple pigtails yield significant improvement over the single pigtail only for the case of short pigtails. Results are compared with other theoretical results and with experiment and show good agreement.
