We present radio interferometric observations of the Algol-type binary system V505 Sagitarii made with the ATNF Compact Array at 6 cm and 3.6 cm over one orbital cycle (1.18 days). We obtained a strong detection of the source (1.5 mJy at 6 cm and 1.4 mJy at 3.6 cm). The radio flux level shows a clear modulation with evidence of eclipses of the emission region at both conjunctions of the binary which may indicate the existence of an intra-binary region of activity. This has important consequences for the details of coronal formation and field interaction in active close binary stars.
