[TowerTalk] Grounding, Lightning & corona discharge

[Tom Rauch]

Just curious, how is the telco connection done in the states
? What is
there to connect to a single point ground?>>

In the USA, all installations come to an entrance box that
has either shunt and series devices for protection or shunt
devices. Older boxes used series carbons with gaps. Newer
boxes have an MOV protection module.

A single ground wire from the shunt protection is clamped to
the power line ground.

This is the national code.

In Atlanta, there was a series of house fires caused by
installers of small dishes NOT using a single point entry
and not grounding the cable shield to the utility ground
through a grounding block. To make it worse, they used trees
as dish supports. The company responsible went out and moved
dishes out of trees, and/or grounded and routed cables
correctly.
