Basic principles of wind power lightning protection for communication base stations

Can radio communication sites be protected from lightning?

The protection from lightning of radio communication sites can be achieved and protection from even direct lightning strikes is possible. The author is familiar with many examples where direct strikes have occurred and full protection has been achieved. The mechanism of a lightning strike must first be fully understood.

How should a lightning protection System (RBS) be formed?

The earthing network of an RBS should be formed by a ring loop surrounding the tower, equipment room and fence, at a minimum. The mean radius re of this ring loop should be not less than l1, as indicated in Figure 1 and this value depends on the lightning protection system (LPS) class and on the soil resistivity.

Is there a systematic approach to lightning protection?

The only time proven method of lightning protection is to adopt a systematic approach. Lightning protection standards, particularly those revised since 1990, advise on this systematic approach.

Where can I find information about lightning protection?

For lightning protection best resources are Polyphasers book the ARRL Handbook along with the book “Grounding and Bonding for the Radio Amateur”. The ARRL Handbook contains good electrical safety information for the amateur radio operator. Links on the next few pages to references and info. Links are also available at:

Why are radio communications stations prone to lightning strikes?

It is not difficult to understand why radio communications stations are so prone to lightning strikes. Sites are generally located on elevated ground and mountain tops and have an antenna tower or mast prominently located to optimize radio coverage to the surrounding areas.

How does a lightning protection system work?

The geometry of the interconnections in and around the building are of vital significance to the effectiveness of the lightning protection system. The objective is to provide a path for the potentially destructive lightning current flowing from the antenna to the AC supply line via a path that does not include the interior of the building.
