![]() More studies are warranted to clarify their relationshhip.Įlectrification (Figure 1) The main charging area in a thunderstorm occurs in the central part of the storm where the air is moving upward rapidly (updraft) and temperatures range from −15 to −25 ☌ (5 to −13 ☏). Lightning is also the major cause of wildfire, and wildfire can contribute to climate change as well. However, lightning may also improve air quality and clean greenhouse gases such as methane from the atmosphere, while creating nitrogen oxide and ozone at the same time. There is growing evidence that lightning activity is increased by particulate emissions (a form of air pollution). The first surviving photograph is from 1882, by William Nicholson Jennings, a photographer who spent half his life capturing pictures of lightning and proving its diversity. The first known photograph of lightning is from 1847, by Thomas Martin Easterly. The fear of lightning is called astraphobia. At all times people have been fascinated by the sight and difference of lightning. Idiomatic expressions derived from lightning, such as the English expression "bolt from the blue", are common across languages. Humans have deified lightning for millennia. Many other observational variants are recognized, including " heat lightning", which can be seen from a great distance but not heard dry lightning, which can cause forest fires and ball lightning, which is rarely observed scientifically. ![]() The three main kinds of lightning are distinguished by where they occur: either inside a single thundercloud (intra-cloud), between two clouds (cloud-to-cloud), or between a cloud and the ground (cloud-to-ground), in which case it is referred to as a lightning strike. Lightning is an atmospheric electrical phenomenon and contributes to the global atmospheric electrical circuit. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Our grounding and surge protection designs ensure your communications equipment is well-protected across all weather events.Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or with one in the atmosphere and on the ground, temporarily neutralizing these in a near-instantaneous release of an average of one gigajoule of energy. Whether you use TV/radio equipment to send/receive communications, or just enjoy radio, a comprehensive tower and antenna lightning protection system (LPS) provides you with invaluable benefits.Īll TV/radio antenna lightning protection systems should be properly grounded to limit damage from lightning and electrical storms. Without the right high mast lightning protection, a storm will damage wiring systems and other expensive components, putting those in your facility in danger. When lightning strikes, antennas and TV/radio towers become prime targets. Beyond interrupting basic TV and radio signals, damaged towers and antennas may prevent the broadcasting of important life-saving messages at times when this information could prove to be the most crucial. This is especially problematic in today’s world, where our reliance on these communications is at an all-time high. Whether you’re considering protection for critical towers, or simply looking into ham radio grounding and lightning protection, implementing a lightning protection system (LPS) on your antennas, towers, and communications structures gives you a safeguard in the event of a lightning strike or electrical storm.ĬOMMUNICATION TOWERS & ANTENNA | CUSTOM LIGHTNING PROTECTIONĬommunications equipment like TV and radio antennas are prone to lightning strikes during extreme weather events such as hurricanes, floods, and tornadoes. Additionally, replacing this apparatus often carries with it a hefty price tag. ![]() In fact, lightning is one of the biggest causes of tv and radio equipment failure. Even a small power surge could interrupt important communications. Many people are hesitant to spend the money to implement customized communications protection or ham radio lightning protection, but the safety of your personnel makes it a worthwhile investment (not to mention the cost of replacing or repairing unprotected structures otherwise).Ī lightning strike can destroy a variety of elements of television and radio apparatuses, including antennas, masts/towers, transmitters, amplifiers, and receivers. WHY YOU NEED LIGHTNING PROTECTION FOR ANTENNAS, RADIO/TV TOWERS, AND STRUCTURES
