CXOU J163802.6-471358 is compact X-ray source which has a 40 arcsec
`tail’, and is identified as a pulsar wind nebula (PWN). The Molonglo
Galactic Plane Survey (MGPS) includes a nearby radio source, offset from
the X-ray position in the same direction as the X-ray tail. However, the
relatively low resolution of the MGPS data do not resolve the structure
of this radio emission in any detail. We present GMRT observations of
this radio trail from this PWN, at 325 and 1280 MHz, with resolutions
down to 5 arcsec. The GMRT observations reveal the radio trail to be a
well defined, linear feature about 90 arcsec in extent. Our Dual
frequency observations do not reveal any evidence of significant
spectral index variation along this radio trail.
