ASR-803 was operating in L-band air surveillance radar intended for use as an terminal area surveillance radar.

It used the G 14 antenna from Selenia with two antenna feeds for low and high beam which was also used in the Italian radar ATCR-22.

The radar failed to gain market acceptance because it was too large and heavy compared to competing radars operating in the S band.
