Grounding an unused cable coax drop
My house previously had cable (before we moved in). We now have satellite. The satellite coax is grounded with a ground block in the demarc box. However, the old cable coax drop from the pole was just left loose in the box. Should that cable coax be grounded as well? It's a two-port ground block, so I could screw the cable coax into it without affecting the satellite grounding.
Thanks!

If you aren't using their system, I don't see why you need to ground it.

Ground it by screwing it into the ground block, then terminate it on the other side? Like this?

Yes. ALL aerial communications wiring must be grounded with an approved grounding device. This is to guide stray currents to the earth from atmospheric disturbances.
OR, have the cable completely removed from the house.

OK, got the cable coax drop screwed in, just have to get the terminator and attach that. Was more of a PITA than I had expected, mainly because of the lengths of coax that I was given to work with.
A sort-of related question: How important is the actual plastic demarc box itself? Mine doesn't seem terribly weatherproof compared to, say, the telco NID, or even to newer coax enclosures. But does it need to be? After all, I've seen coax ground blocks attached directly to the side of a house.
