You run the grounding wire as close to the other wires as possible to avoid
"ground loops (GL)". The EM field from a lightning will induce voltage in any
GL with following current.
A direct hit on the tower will not give anything different with ground wire
close to the coax or not. A nearby strike will see the difference.
I have a 6" wide AL strip between my tower and shack (only a few feet long
though) and the feed cables are right on top of the strip.

Subject: [TowerTalk] Antenna to Shack Ground Connection
Dear Group:
I am now ready to connect the tower grounding rod network to the shack
grounding system. The crank-up tower is about 30 feet from the shack. Is it
preferable to run the ground connection between the two along with signal
cables? Or is it better to run the grounding connection not so close to the
signal cables? I've seen people do it both ways, and can see a possible
benefit
either way, but a lightning strike could throw either idea out the window.
Thanks,
Norm
