  We present new radio observations of the recently identified, young Galactic
supernova remnant (SNR) RX J0852.0-4622 (G266.2-01.2) made at 1.40 GHz with a
resolution of 14.9 arcmin. These results, along with other radio observations
from the literature, are used to derive the extent, morphology and radio
spectrum of the remnant. The possible age and distance to this remnant are
discussed, along with the consequences of its properties - especially its low
radio surface brightness - for statistical studies of Galactic SNRs. The
extended features identified by Combi et al. (1999) are considered, and we
conclude that these are probably unrelated to the new remnant. If RX
J0852.0-4622 is nearby, as is suggested by the available gamma-ray data, then
the range of intrinsic radio luminosities for SNRs of the same diameter may be
much larger than was previously thought.
