A system for introducing N cables into an anechoic chamber, where N.gtoreq.1 comprising a channel having an electrically conductive interior, and an electrically conductive entrance in communication with the chamber such that the cables can extend from the channel into the chamber. The system is also comprised of a housing made of a conductive material disposed such that it forms an electrically conductive seal with the channel entrance. There is also a lossy material disposed inside and essentially filling the housing through which the cables extend. In a preferred embodiment, electricaly magnetic radiation having a frequency of up to 100 GHZ is essentially prevented from escaping the chamber. The present invention also pertains to an interface through which N cables, where N.gtoreq.1, are introduced into a first region having electromagnetic radiation with a frequency at least above 10 GHZ from a second region essentially isolated from the first region such that essentially no electromagnetic radiation between a frequency of 10 GHZ and 100 GHZ escapes from the first region to the second region through the interface.
