I have used various lightning dissapators in the past.
These systems can greatly reduce lightning but the installation of these systems can be very pricey. The whole system works only as well as the ground system.
That being said they can be effective. Their was and maybe still is..a company out of Clearwater FL. called Lightning Masters who also are pretty good at this.
Which is part of the problem in Florida. I've spent more than $100,000 trying to build a decent ground for Florida Gas Transmission Compressor stations.
