As Mike stated there are companies that make lightning dissipation rods. These look like giant pipe cleaners. I've seen them on sailboats for years as well as barns out in the country.
A gentlemen down in Maryland a few years back with a home dome 6 took a direct hit. It fried everything inside the observatory. He was running all Astro Physics equipment as well. I saw the OTA at a company in Maryland and it was destroyed. The kicker is the guy is a local weather forecaster. OUCH.
Something else to consider is the application of rebar used in concrete piers. It was told that lightning can effect your equipment even if it is a nearby ground strike. The strike could follow through the ground and make easy contact with the rebar thus causing a host of issues.
Just a couple thoughts.
Clear skies,
