Where I can get Ford coaxial cable for my camper?

SMA connectors, also sold as RF. Similar size, so cutting original cable in 1/2 and adding connectors with extension between did the trick.
From last time I was doing precision soldering my eyesight went from "Hawk" to "glasses #2" but it still work.
Did dry test on driveway and truck only and it works. They are not weather-tight so will have some wrapping to do.
Will load camper tonight, or Monday, so time allows will post some pictures.
