Adelphia’s Cable System in Yuma, Arizona, has been providing the Yuma Proving Grounds with Cable TV service for several years with a 54 – 550MHz link from Cable AML.

The wireless HFC extension crosses the Colorado River at one of its widest points. “The Cable AML dual-frequency link has been performing perfectly,” said Hugh Williams.
