Couple things here. Like the others aside, water intrusion in the broken cable jacket is bad

But, why is the cable jacket (black part) broken in the first place? It’s probably been outside a long time and the outer portion is brittle but also it appears to be stressed. The cable looks like it’s pulled tightly instead of being secured in place with enough slack to keep tension off the connector

In other words, the cable was pulled so tight that over time slightly bumping it or wind battering it caused the jacket to break, and allowed water to intrude and degrade the cable from inside. At least that’s my guess just from the limited info I see in this pic

So hopefully the replacement cable has some slack to it and doesn’t break in that spot due to tension or stress.

You can buy some self adhering or Vulcanizing tape and wrap the connections to weatherproof the new connections after it’s replaced
