We put gas tube lightning protectors at the bottom of every cable run
for our microwave (5, 6 and 11Ghz bands) links. At the half-way point
and at the top we install grounding kits to ground the shield of the
cable to a good ground. The Motorola R56 standards have some good tips
and standards to use for grounding of towers and feed lines. Feed line
ground kits aren't always cheap, but the first time they protect your
equipment from a lightning strike, they have already paid for themselves!
