You might like to look at the latest Motorola R56 Installation standards manual. It's very comprehensive. Has good section on grounding and protective devices.
Yes, a good grounding system and a full lightning and surge protection of an RF site doesn't come cheap. But if you live in Florida the lightning capital of USA or similar location then every step you can take can save really big bucks in system damage and give you more system up time. Back in the mid 1990's I did a R56 installation of a 800MHZ trunking system in Manaus, Amazonas in Brazil. This was co-located with a 50KW TV and 20KW FM radio site and also at the same site he was running the local ISP vial dial in landlines. The customer initially thought we were really overdoing the trunking installation by following R56. But after a massive direct strike which took out both broadcast transmitters and burnt out every one of his hundred or so Modems, but thanks to our following the R56 installation guidelines the 800Mhz site kept on happily trunking. He then read with great interest the R56 manual and applied it to his whole installation.
