Abstract
The four-image gravitational lens system MG 0414+0534 was observed with the VLA at 1.4, 5, 8, 15, and 22 GHz. The 15 and 22 GHz images reveal structure in the components which is consistent with that seen at other wavelengths. There was no detection of other extended emission, nor were there detections of the lensing galaxy or the "component x" seen in optical images. Detections of polarized emission show that the fractional polarized intensity is 1%. The observed properties of MG 0414 suggest that it is a GHz-peaked spectrum source.Keywords
