Coax And Lightning?

Those may be ok for supplemental protection, but you should still have the overall site grounding and bonding taken care of first and foremost.
An easy option that you could build yourself uses a Tee connector and a piece of cable to place the entire antenna at DC ground. Using RG8 or RG58, strip the coax and solder the inner and outer conductors together six feet out from the center of the Tee. Place the Tee anywhere convenient in the system. Can attach the far end of the cable to a ground connection somewhere as well. This is for 27MHz only. At other frequencies the length will be different.

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.
