A connector containing data pins for video signals and a coax pin for an antenna signal can permit a personal computer (PC) to use an integrated antenna in an external display device, with a single connector providing both video and radio frequency communication signals between those two devices. This connector may be used in place of the standard 15-pin VGA connector. In various embodiments, this connector may be contained in the PC, in the external display device, or in both. In some embodiments, this connector may be in an adaptor cable for use between the PC and the external display device.
