I would like suggestions on how to earth/ground two aluminium masts, one which has a Penta Satellite dish and the other which has a Log Periodic freeview aerial and dab. I would like to Earth both of these against lightening and noise, they are only about three feet apart and above a porch.

I would like specific items to purchase to do the job keeping it as aesthetically pleasing as possible. I have seen grounding rods and earth clamps for attaching cable to the grounding rod and to attach to the masts but the issue is more making the connection between the two masts and the grounding rod, I was hoping for something more aesthetically pleasing than a green cable. Whatever is used needs to be joined in some way because I don't want two cables going down my wall to the ground rod.
