[6] An extended radio lobe was also discovered in 3C 380, having a low spectral index when compared to those at decimeter wavelengths.

Based on VLBI observations, it is shown to be resolved when travelling in a transverse direction, however it also shows signs of rapid brightness variations unlike other nuclear jets indicating phase effects play a role in causing these changes.

Apart from that, the jet shows superluminal motion[12] and a Faraday rotation gradient measuring 70-200 parsecs in width across it.

[13] Radio imaging Very Long Baseline Array (VLBA) also finds the jet is extending in a northwest direction.

Together, these knots are found laid over lobelike emission which in turn, is stretched out in both east and northeast directions.
