Abstract
The four-image gravitational lens system MG 0414+0534 was observed wit h the VLA at 1.4, 5, 8, 15, and 22 GHz. The 15 and 22 GHz images revea l structure in the components which is consistent with that seen at ot her wavelengths. There was no detection of other extended emission, no r were there detections of the lensing galaxy or the ''component x'' s een in optical images. Detections of polarized emission show that the fractional polarized intensity is less than or similar to 1%. The obse rved properties of MG 0414 suggest that it is a GHz-peaked spectrum so urce.
