Almost everywhere! Virtually all populated regions have varying incidences of lightning strikes. There is meaningful risk worldwide over the lifetime of typical tower and antenna systems. Facilities outside of "lightning belts" should at least be minimally protected while critical infrastructure and flammable/explosive risks must be protected wherever they are. Extreme protection measures are mandatory in areas of intense lightning risk!
The largest class of technical structures needing lightning protection in the world today is towers and their antennas, particularly for wireless communications and broadcasting.
In less than 30 years, cellular mobile towers and antenna structures have proliferated on every continent, and are perfect lightning targets! To a lesser extent, AM, FM, and TV towers have also sprouted, sometimes sharing with cell systems. Not only are the towers at lightning risk, but also the cellular, public safety, broadcast, and communications antennas mounted on them. At risk too, are the attached cell site equipment, radio transmitters, coaxial cables, and tower light systems.
Related to communications towers are other vertical technical structures such as drilling rigs, flare towers, wind turbines, tanks, environmental monitor masts, and industrial structures.
At the same time, portable and temporary high value assets have flourished. From satellite antennas to mobile command posts, work camps to mobile power systems, important assets and their personnel are being put in harm’s way from lightning discharges.
LBA specializes in the lightning protection of these technical assets. With 50 years’ experience worldwide in electromagnetic protection, broadcasting and wireless communications, we have the expertise to design and furnish best protection for these systems.
Lightning Mast Protection Systems
Area protection for fixed and portable assets
LBA Technology offers the PLP-30 family of fixed and portable lightning protection masts and kits. Based on a light weight, rugged 30 foot (9.1m) aluminum mast; various mounting styles, grounding systems, and UL – Listed air terminals are offered. PLP-30 lightning mast components are under 9 feet (2.7m) long for easy surface or air transport and rapid field installation.
• Camps, portable buildings or vehicles
• Petroleum, water pumping and utilities
• Emergency NGO or military command posts
• Solar cell and satellite dish installations
• Environmental monitoring facilities
• Rooftop installations not readily protected by conventional terminals
* Patents pending on this unique lightning mast
PLP-30 Lightning Masts are recommended for a wide range of lightning protection applications where it is impossible or undesirable to attach conventional lightning terminals. Other models in the series share the same attributes and differ only in height and weight.
PLP- 30 Lightning Masts provide a cone of protection within which lightning charges are diverted to the mast and grounded instead of to the protected object. Multiple PLP-30 masts may be used to protect extended areas. Protected areas may be determined by use of the widely accepted “rolling sphere” concept. For example, a single PLP-30 mast will protect 8 foot (2.4 m) high portable buildings wholly within a 40 foot (12.2 m) radius. An array of five PLP-30 masts will protect a camp of portable buildings within a 25,000 square foot (2350 m2) area. Consult LBA Technology for specific layouts you wish to protect.
The PLP-30 Lightning Mast is furnished with a UL-Listed streamer retarding air terminal. Streamer retarding (static dissipation) terminals have been shown to reduce the probability of lightning strikes, as well as divert them to ground, should they occur. Static dissipation systems work by dissipating static charge. Static dissipation arrays provide, in effect, a "low resistance" route for static ground charge to reach the atmosphere preventing a buildup of the ground charge to the value necessary to trigger a strike.
The PLP-30 mast includes a universal base section, three screw-together mast sections, and a screw-in air terminal. The screw couplings are of a special proprietary design for maximum current contact area and high mechanical strength. The assembled weight is only 45 pounds (20.5kg)
The PLP-30 is rated to sustain 100 mph (160 kph) hurricane winds. The PLP-30 utilizes the same construction system as LBA’s “Power-Topper” antenna top loading systems which have served for over 30 years in many parts of the world.
PLP-30 Deployment Options: The PLP-30 and its options are all designed for convenient, fast deployment with minimum resources. Assembly and disassembly of the PLP-30 mast is a simple one person procedure, using only common hand tools, and typically requires under an hour. Once assembled, the PLP-30 mast may be readily mated with an appropriate support system. The universal base section of the mast is designed to interface with an optional fixed base (FB-1), portable base (PB-1), or customer supplied base. The base section is provided with attachements for grounding conductors.
PLP-30PK Portable Kitted System: All necessary components for rapid shipping and field deployment of the PLP-30 are available in a kit. The PLP-30PK kit includes a PLP-30 Lightning Mast, a PB-1 Portable Mount System, six HDS-12 hold-down stakes, three GR-4 four foot (1.2 m) ground rods and bimetal grounding attachments, three GC-4 #4 copper ground cables, and a heavy duty ripstop nylon transport carrier. Packed length is under 108” (2.7m) and weight under 100# (45kg), allowing for easy handling and air/surface express shipment. NOTE: All other PLP-(*) versions are also available in the same kit system. Weights will vary.
PB-1 - Portable Base Mount: The PB-1 consists of three horizontal 3 foot (0.9m) aluminum beams and hardware for direct placement on earth, with attachment to the PLP-(*) base section. Three bracing beams and hardware are provided for attachment between the end of each horizontal member and the base tube section. Holes are provided in the horizontal beams for customer furnished hold-down stakes. Alternatively, sandbags may be used to secure the mount. With permanent hold-down bolts, the PB-1 may also be used as a fixed mount. The PB-1 base assembly weight is only 15 pounds (6.8kg).
FB-1 Fixed Base Mount: The FB-1 includes a 10” (254mm) square baseplate with holes provided for attachment to customer furnished ½” (12.7mm) hold-down bolts. Typically these may be concrete embedded or welded to a structural support. The FB-1 includes a bimetal fitting for attachment of customer provided ground system. The FB-1 base weight is only 8 pounds (3.6kg).
Alternate Installations: The PLP-(*) may be installed with customer furnished brackets to buildings or structural supports. The base section includes three sturdy ribs
The PLP-(*) may also be temporarily installed in an augured and backfilled hole, or embedded in concrete for a more permanent installation. In these cases, the length of the PDP-(*) will be reduced by the depth of embedment. Soil and corrosion issues are the responsibility of the user and should be carefull considered in using this approach.
All products and options above are designed to be UPS/FedEx shippable by ground or air where rapid response is required.
The models shown above are standard LBA Technology products. Custom configurations are available. To quote your specific requirements, or to order, please consult Byron Johnson, Byron.email@example.com or 252-757-0279.
LBA Lightning Dissipator Arrays
LBA offers a wide variety of lightning air terminals in the form of lightning dissipaters. Sometimes called a static dissipater, or static dissipation array, this relatively new and advanced air terminal replaces conventional lightning rods in most applications. It functions as a streamer retarding air terminal.
Static dissipation array generically describes a system using point discharge phenomenon to protect towers and antennas and the area around them from a lightning strike. Static dissipation arrays function, as the name implies, by dissipating static electrical charge. Among design factors, the radius of the dissipater electrode cross-section is critical because the process which enables dissipation of static ground charge to the atmosphere is related to electric field intensity (and flux density) surrounding the lightning dissipater. Static dissipation arrays provide, in effect, a "low resistance" route for static ground charge to reach the atmosphere, thus preventing a buildup of the ground charge to the value necessary to trigger a strike on the protected object.
Since a static dissipation system must provide a low resistance path to the atmosphere, it seems logical to provide as many discharge points as reasonably possible. By using a large number of air terminal points one can compensate for any loss of efficiency from a theoretical maximum, and spread the dissipater elements over more of the cross-section area of the tower or antenna structure.
All objects have natural dissipation points. On a tower structure, charge tends to gather at, and dissipate from the tower top, antennas and antenna mounts, and from corners. The most effective way to mount a dissipater in terms of structure, weight, wind loading, cost and aesthetics is to enhance this natural dissipation by supporting the dissipater from the structure itself at these natural dissipation points. Since most antenna and tower structures are steel, direct attachment provides excellent conductivity. As a practical matter, the dissipater configuration should be tailored to the structure, not vice versa.
Our lightning dissipaters are available in configurations which can protect the entire tower structure, or just individual cellular antennas. To accomplish this, dissipaters are available in linear, spot, and candelabra styles. From our proprietary products to those of LBA partner suppliers, our products meet highest quality and reliability standards, certified by standards organizations as required. Consult with LBA for the exact mix of products to most effectively protect your antenna or tower system.

Description: The Linear Dissipater Array (LDA) is designed to retard streamer formation and to enhance the natural dissipation characteristic of the structure, consistent with aesthetic considerations. A linear dissipater element consists of a central cable with dissipation electrodes inserted continuously within the wind of the cable. Each element is two feet long. The configuration of LDA elements and supporting structure is dependent upon the specifics of the tower top or other structure being protected. Each array is custom designed and quoted.
Application: Linear Dissipation Arrays are suited to large exposed structures where a high level of static charge dissipation is required. Such structures include broadcast and communications towers, large light structures, bridge spans, flare pipes, oil rigs, and industrial process equipment.
Description:Candelabra Dissipater Arrays (CDA) typically include four individual brush-style dissipater elements on brackets around the top of a 1/2" x 13 threaded supporting rod. Versions are available on 18", 24” and 48” stainless rods. All CDA’s are Underwriter Laboratories listed as “air terminals” and may be used as part of a “Master Label” system. These CDA’s are patent protected.
Application:A CDA is appropriate for use wherever an air terminal (lightning rod) is appropriate and static dissipating qualities are desired. The addition of the streamer retarding CDA secures the benefits of the latest technology in static dissipation while retaining the proven protection of the conventional air terminal. It is particularly suited to protecting aviation warning lights atop power transmission towers and other structures because its thin support rod places the dissipaters above the beacon without occulting its warning beam. The CDA is also ideal for protecting structures like smaller towers, light poles, and satellite dishes.
Description:Spot dissipater elements (SDE) are patent protected brush-style dissipaters. They consist of a multiplicity of thin stainless steel wires that are mounted in a stainless tube. The tube is provided with convenient mounting holes. The stainless construction makes the spot dissipaters highly corrosion resistant. The basic SDE consists of a “brush” of stainless wires 4” long in a 3” long tube, for a total length of 7”. With appropriate fittings, several variants are available. Typical are:
Application:Spot dissipaters are multipurpose devices. Their lightweight and convenient mounting facilitate protection of structural features and devices that do not require the larger LDA and CDA dissipaters. For instance, handrails, lighting fixtures, small antennas, poles, storage tanks, shelters, pumps, and many more devices may be protected. More than one SDE may be attached along the perimeter of tanks or similar assets. For that use, a spacing of 10 to 20 feet is typical. The SDE-22A is specifically designed to mount to the tips of DC grounded radio antennas. The SDE-22B is intended to attach to the top of lightning protection poles and flagpoles.
Description: These Air Terminals incorporate the “brush” of an SDE in the end of a conventional air terminal rod. These units are mad e solid copper or aluminum and include a standard ½” screw thread on the base to fit most lightning system bases and grounding fixtures. These terminals are Underwriter Laboratories listed. Typical variants are:
Application:Typical applications are on building structures and equipment. These can be used in place of a DAT-112C Air Terminal standard air terminal in a lightning protection system built to UL-96A and NFPA 780 specifications.
Use the LRE-series of lightning air terminal extenders to facilitate protection of sensitive electronic, communication, and mechanical assets. The LRE-series of extenders adds a critical step in the quest to put lightning where it belongs, the ground.
Conventional practice has been to place lightning rods or air terminals directly on the structure of outdoor air handling units, stacks, control boxes, and antenna, CCTV, and lighting masts. This type of arrangement permits lightning strike charges to flow not only through the mast or structure, but through the attached sensitive equipment as well.
LRE extenders solve the problem by keeping the air terminal well above and independently attached below the protected equipment. This more effectively controls the lighting path. Charges are routed directly to ground, bypassing exposed equipment or cable routings.
Select Models LRE-8 and LRE-14 to elevate air terminals eight feet and fourteen feet, respectively. The extenders are constructed of heavy-duty aluminum and meet NFPA requirements. They can be used with most UL-listed air terminals. LRE-series extenders are designed for installation with an assortment of mounting options, including a non-penetrating roof mount.
LRE lightning protection hardware is particularly effective when coupled with the LBA series of field dissipater air terminals and candelabra dissipaters. Unlike conventional air terminals, these charge dissipation air terminals bleed off accumulating electrostatic energy, reducing the potential for actual lightning strikes. Consult LBA for recommendations on appropriate selections.

LBA does not claim that these products are 100% effective in preventing lightning strikes. At the present collective level of understanding of the lightning phenomenon, the behavior of lightning events is to some degree unpredictable. These products, however, do influence the course of lightning strikes and thereby are believed to reduce the incidence of direct strikes
Proper grounding of the PLP-30 and all lightning protective devices is very important. LBA grounding notes and accessories are offered for user convenience only. It is the user’s sole responsibility to determine and apply installation and grounding practices appropriate to their application. The standards of the Underwriter’s Laboratories (UL), National Fire Prevention Association (NFPA), and appropriate other standards groups should be carefully followed.
