And just to be careful, you might also point out that 6 foot 'stub' would only be for an 11 meter antenna's feed line. It would have to be a different length for different bands so not usable on multi-band antennas.
I think those lightning arrestors shown in post #31 have been around almost forever, and can't 'arrest' lightning at all, at least not soon enough to help. I've only taken one apart so the one shown could be different (wouldn't bet on it though). They are 'spark-gap' type arrestors.

Those surge protectors limit the surge travelling along the center conductor of the coaxial cable. They will not control or direct ground currents. I'd consider them only as supplemental protection. Without correcting the overall installation, including proper routing of transmission lines, they will have little affect.

All this seems to look like to me is to run a ground from your radio?
