Anybody do coax cable installs?

The existing cable functions, but there seems to be quite a bit of resistance in the line. I've been told that the SNR is high. I figure after 20+ years of being in the elements, it wouldn't hurt to replace it. The line is on the outside of home and punched through an exterior wall (about 12" above the ground).

Who’s telling you that? Comcast? They should be the ones replacing it, if its the service feed that is coming in it’s theirs to maintain.
