The lines on the outside of the house only extend about 4 inches past the wall. Would a photo of the ends help to determine the level of corrosion?

I considered this during testing and removed the wall plates to connect the MoCA adapter directly to the cable behind the plate.

Re-terminating the lines outside is something I’ll consider, but I’m concerned I won’t have enough room to work with as they only extend out of the wall about 4 inches each.
