You may want to download the Motorola R56 pdf file online. Also QRZ
dot com has a 3 part forum on station grounding hosted by a PE who
installs and inspects cell tower sites. Both are a very interesting
and informative read.
bear in mind that R56 (and cell towers, and the document from the FAA
about control tower radio installations) are for commercial
installations with 24/7 requirements.
Note also that the systems involved are VHF/UHF, feedlines are generally
hard line, bonded to the tower top and bottom, and their only concern
(as far as grounding and bonding is concerned) is lightning protection.
Some of our antennas are on towers, some are not.
