Surge Protection for Base Stations
OVERVIEW
Today’s increased reliance on very sensitiveW electronics makes surge protection an important topic for Telecommunication. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.
This article discusses various configurations of Base Stations from cabinets to large shelters to help you develop a comprehensive surge mitigation strategy. Each section will provide a recommendation on exactly which protector to use for your equipment and where to install these Surge Protective Devices for Base Stations.

Surge Threats
The Base station not only includes sensitive equipment such as the Baseband Unit (BBU) and the equipment for RF but, in addition, includes auxillary equipment as well. All parts of the base station are subject to surge transients.
The use of surge protection on radio and televison equipment is also covered within the NEC. Article 810.6, Antenna Lead-In Protectors, requires a UL497E Listed surge protector.
