The HyGain company has built antenna rotators since at least the late 50's and continues today; although just extra-large models for commercial and military use. They purchased the CDE line in late 1981. The TELEX corporation bought HyGain in 1982 and built them until selling the complete HyGain line to MFJ in May 1999. Following are several pictures which will help to identify them.
