High frequency AC tends to travel near the surface of metals. A company I used to work for used to exploit this skin effect to look for cracks in welded joints and pipes, the voltage drop was higher in a cracked sample as the current travelled along the surface and up and down the sides of the crack. In an OK sample, it didn't pass through as much metal, so the potential drop was smaller. So it is entirely possible that a corroded cable can affect the higher frequencies, but how corroded it needs to be and how high the frequencies would have to be would be hard to tell.
