All good ideas.
Diodes may mess up readings if the rf level is too high but protection is more important.
May want to experiment where you ground the shield. Probably close to to the controller but not to the controller.
It definitely can be fixed.
In my days as a broadcast engineer. Built a 8051 based controllers to control antenna switching and tower lights for a directional am station. It was all unshielded. There was so much rf that you would get an rf burn if you touched it. Was using 25 pair phone cable. Also was getting frequent direct lightening hits. Worked at least 10 years without any repairs.
