4C 11.50 is classified to have a compact source. When observed in 1974, it is found to contain a dominate compact component coincident together in the position of the quasar with two other components displaying a steep [[spectrum]].<ref>{{Cite journal |last1=Argue |first1=A.

New observations made with [[Very-long-baseline interferometry|Very Long Baseline Interferometry]] (VLBI) and [[Very Large Array]] (VLA) found the radio structure of 4C 11.50 as different. On [[Minute and second of arc|milliarcsecond]] scales, the nucleus of the source appears as weak without any presence of any extended structures. There are two components, mainly a slight resolved component and a weak feature. Observations on large-scale would find the quasar has a much detailed double-lobed structure and a [[Astrophysical jet|radio jet]] that is described as straight, leading towards the southeastern direction from the radio core. However, only two jet knots and the northwestern hot spot feature do exhibit signs of [[linear polarization]].<ref>{{Cite journal |last1=Hooimeyer |first1=J. R. A. |last2=Schilizzi |first2=R.
