Dave,
You are correct. That would eliminate both lightning and RF problems.
At the moment, the drawback is the cost. Fiber cable is kinda steep. This is unless there is a low cost (HEY, I'm a HAM and we are noted for being stingy) source for the cable.
This is the method I would love to use.
Maybe on E-day (no copyright infringement here!).

Again, my Thanks to All.
