VLA observations of the radio emission at 1465 and 4885 MHz of Sco X-1 confirm the collinear triple structure of the object. Simultaneous VLBI observations at 5010 MHz were also made. We present strong evidence that the three components of Sco X-1 are physically associated. We also discuss the likelihood that a physical phenomenon similar to that occurring in extragalactic radio sources occurs in Sco X-1 but at a much lower energy level. A previously unknown radio source 20 arcmin away from Sco X-1 has been found to lie nearly along the radio axis formed by the components of Sco X-1. This source is probably unrelated to Sco X-1.
