  ESO422-G028 denotes the very center cD-galaxy of the giant radio source
B0503-286 (Saripalli et al. 1986, Subrahmanya and Hunstead, 1986). The angular
extent of the associated radio structure is about 42.4 arcmin, which
corresponds to a linear size of 1.89 Mpc (with Omega_M=0.27, Omega_Lambda=0.73,
and H_0=71 km/s/Mpc). Here we present new high-frequency total-power and
polarization radio maps obtained with the Effelsberg 100-m dish. In addition,
we correlate the radio data with optical and X-ray observations to investigate
the physical conditions of both, the host galaxy and the extended structure.
