[TowerTalk] Ground resistance

[Keith Dutson]

>The most dirty words in lightning protection are LONG and INDUCTANCE. More
copper plates solve nothing except acting as a place to bond all the antenna
ground connections together, and those connections are only effective if
they are very short.

These should always be used together when discussing lightning protection.
Short is of course relative to the inductance generated at about 1MHz.  A
thin wire 3 feet long may be worse than a 3 inch copper strap 50 feet long.

Above all, NEVER assume that a well-engineered ground system will prevent
lightning damage.  Get some good insurance to protect your home and
equipment against that rare direct hit.
