The Very Large Array and the Soft X-ray Telescope aboard the Yohkoh satellite observed the rapid growth and decay of a so-called ``anemone'' active region on 3-6 April (AR 7124). In general, discrete coronal loop systems are rarely resolved at radio wavelengths due to optical depth effects and scattering. In the case of AR 7124, however, several discrete loops or loop systems are resolved by both the VLA and the SXT, probably due to its unusual ``anemone''-like morphology. Furthermore, the region exhibited a significant amount of variability, especially on April 3, marked by many subflares and intensity changes as has been reported in flare patrol observations. In the present study, physical parameters derived from multiband radio and soft x-ray techniques for discrete loops are compared. The temporal evolution of these parameters is also examined.
