Moving modem best cable

Hello Internet,

I have a SB8200 i would like to place on the opposite side of the house looking at cable to run from the point cox touches my house across (mostly under the roof but still outside) and then into the wall in the office.

looking for cable suggestions the two i was looking at are below.

https://www.amazon.com/dp/B003FW0X6Q/

https://www.amazon.com/dp/B09TNBC384

both are RG6 and 70ohms which i believe are the two main requirements. any suggestions?

Edit: went with Media Bridge Cable. LOVE IT.

HUGE win, with all my powers dropping from 11's to 6dBmV's my understanding is that is a good thing. And looking at the event log I haven't gotten a single power warning pop up so I'm stoked about that. thanks for the tips all.

    Either of those should be adequate. - ChrisJ - Forums Moderator

    Is it at all practical to go through the wall at the demarc, place the modem there, and then using ethernet to the router? I got rid of a fair amount of noise when I ditched the coax running from one side of the house to the other, and that was internal.

      i really dont want to run the Ethernet cable inside the house since even my cleanest job of running it in the corners i still wouldn't be the happiest to see.

      i didnt ask it in the post but i was originally trying to look up and see if 100ft coax vs 100ft ethernet which would be better on the system.

    I thought Cox used quad shielded RG6. Not saying tri shielded won't work, but something to consider.

      If it's a short run, demark in wall to modem, tri shield should be fine. I have a 20 ft run that is quad shielded, but a 5 ft run, tri should be good.

        The coaxial the OP pointed to was 100 feet. That's why I suggested quad shield. However all the quad shield I can find is 75ohm and not 70. Do you think that makes a big difference?
