Abstract: In one aspect, a rotary connector having a longitudinal axis includes a first metal portion including a groove about the longitudinal axis. The rotary connector also includes a second metal portion and a spring disposed in the groove and having metal contact with the first portion and the second portion. One of the first metal portion or the second metal portion is configured to rotate about the longitudinal axis and the other of the first metal portion or the second metal portion is configured to remain substantially rotationally fixed with respect to the longitudinal axis. The rotary connector may be used for electromagnetic interference (EMI) shielding with antenna pedestals.

Abstract: In one aspect, an antenna pedestal includes a body having an inner cavity. The antenna pedestal includes a portal structure to access the inner cavity of the antenna pedestal. The portal structure also includes a threaded structure disposed around a portal accessing the inner cavity and comprising threads and a cover comprising threads configured to engage the threads of the threaded structure to close the portal. In another aspect, a portal structure to access an inner cavity of a body includes a threaded structure disposed around a portal accessing the inner cavity of the body and a cover that includes threads configured to engage the threads of the threaded structure and configured to be placed over the port to provide electromagnetic interference (EMI) shielding when the cover and the threaded structure are screwed together. One or more of the aspects above may be used for EMI shielding in antenna pedestals.
