I have a question about grounding.
I will have two short shielded cables with signal wires inside, located at the top of a tower. The cables have a grounding wire inside shorted to their foil shields to prevent the foil from building a charge.
I have two choices for terminating the grounding wire. (I only plan to terminate it at one end to avoid ground loops.)
A) I can attach it to the metal at the top of the tower. Let's say this metal body is ungrounded but it's decently big.
B) I can attach the grounding wires to signal ground which has to travel down long wires of 75 ft before it reaches its source.
Is there a clear better option for this? Does it even matter which I pick? I would appreciate any insight.
