Coax on left side of coupling is ISPs with ground. Coax on right side goes to my house.

  1. Do I need to ground the coax to my house? I see ISP has it grounded but if I did ground the run to my house idk what I would attach the ground wire to when it comes inside my house.

2.will RG6 standard be fine for being hung exteriorly.

  1. Do I need the Moca filter ? I have Cox and I only use their internet services, nothing else. 500mbps plan.
