Abstract: We present images of the supernova remnant N206 in the Large Magellanic Cloud, taken with the Australia Telescope Compact Array at 3 and 6 cm. Based on our data and previously published flux densities, the spectral index of N206 is -0.27+-0.06. The 6-cm radio morphology shows a filled center morphology, which along with the spectral index has led us to classify this remnant as Crab-type. Most interesting is the discovery of a peculiar linear feature previously undetected at any wavelength. The feature lies to the east of the center of the remnant, stretching from about one-fourth to three-fourths of the remnant's radius. It is wedge-shaped, with a steady opening angle from an apex on the eastern side. The feature resembles the disturbance expected from an object moving through the material supersonically. We present arguments suggesting that the linear feature may have been produced by the passage of a low-mass companion star ejected at about 800 km/s from a binary system whose other member was the star responsible for the supernova explosion.
