Nice solution. Were you tempted to mod the cable to shielded RJ45 connections to allow Dishy Mcflatface to be used elsewhere, or even buy an additional cable?
I wasn’t as I’ve configured it already so it can be used away from the vehicle. The cable is all stored in the small box on the roof so that I may run the cable out into a field and hook up the dish away from the vehicle, should topographical/foliage conditions dictate I do.
