Anritsu introduces New PIM Master options for top of tower testing in key bands
Anritsu Company has introduced three frequency options for its industry-leading PIM Master MW82119A Passive Intermodulation (PIM) high-power, battery-operated, portable PIM test analyzer. The new options provide wireless field engineers and technicians with the first battery-operated handheld analyzers that can accurately conduct "top of the tower" PIM measurements in the LTE 800 MHz and UMTS 2100 MHz bands, in addition to the LTE 2600 MHz band.
The new options have been specifically developed to address the top bands planned for LTE network deployments, and can help ensure LTE networks do not suffer from lower data throughput caused by PIM interference. Coupled with the battery operation, small size, and ability to perform 40W PIM testing, the new options make the PIM Master MW82119A well suited for deploying, installing, and maintaining LTE networks using Remote Radio Heads (RRHs) at the top of the tower. The PIM Master MW82119A can also be used to measure PIM at traditional macro site installations, as well as in Distributed Antenna Systems (DAS).
The three new frequency options extend the PIM Master MW82119A family to nine analyzers. Six other models are available to address major frequency ranges, including the upper and lower 700 MHz, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 1900/2100 MHz bands. All PIM Master MW82119A analyzers incorporate Distance-to-PIM (DTP) technology, allowing tower contractors, maintenance contractors, and wireless service provider field technicians to pinpoint PIM problems, whether they are on the tower or outside the antenna system. The analyzers' ability to test at 40W allows the PIM Master MW82119A to locate faults that conventional 20W test solutions might miss, such as intermittent and power-sensitive PIM problems.
As with all Anritsu handheld test solutions, the PIM Master MW82119A is designed to withstand transportation shock, vibration, and harsh outdoor test conditions associated with cell site deployment, installation, and maintenance. Testing is simplified by the analyzer's ability to save and recall test set ups for standardized testing, and limit lines can be set for visual and/or audible pass/fail criteria. Anritsu's Line Sweep Tools can be used to manage PIM Master MW82119A measurements, and generate reports that combine VSWR data as well as PIM data into a unified site report. PIM measurements can be tagged with the GPS location when the analyzers are equipped with the GPS option.
The PIM Master MW82119A delivery is six weeks.

Anritsu's new PIM unit utilizes 40 Watts
to simulate real-world conditions
Anritsu Company has introduced the MW8208A PIM Master, an innovative test solution that brings the inherent advantages of Anritsu's patented Distance-to-PIM technology to 850 MHz cellular band applications.
Unique to Anritsu, Distance-to-PIM helps make the MW8208A a comprehensive trouble-finding tool that allows field technicians and engineers responsible for deploying, installing, and maintaining wireless networks to accurately and quickly locate the source of passive intermodulation (PIM), whether it is in the base station antenna system or in the surrounding environment.
With the MW8208A PIM Master, users can uncover the distance and relative magnitude of all static PIM faults simultaneously, including those resulting from dirty connectors, corroded connectors, over-torqued connectors, and microscopic arcing connectors.
PIM Master can also accurately locate PIM outside the antenna system - the only test solution that can do so. Similar to Anritsu's market-changing Distance-to-Fault technology designed into its Site Master cable and antenna analyzers, Distance-to-PIM helps eliminate one of the biggest problems facing wireless network deployment and operation.
The MW8208A generates two high-power tones in the transmit band of a base station and can measure the 3rd, 5th, and 7th order intermodulation products in the receive band coming down the same cable. Utilizing the GPS feature on the Anritsu handheld analyzers, users can record the location of the measurement
Another advantage of the MW8208A is its 40 W testing, compared to alternative methods that only measure at 20 W.
Utilizing 40 Watts simulates real-world power that activates the PIM that might not otherwise be activated by 20 Watt systems. In addition, using double the power allows PIM Master to locate intermittent failures due to light corrosion, high-traffic loading, or changing weather conditions.

AT&T starts selling cell tower in a suitcase
AT&T announced that it is now selling small, portable cellular antennas that will allow corporate and government customers to provide their own wireless coverage in remote or disaster-struck areas.
The carrier's "Fly Away" Remote Mobility Zone is effectively a small cell tower that packs into a suitcase.
The satellite dish is carried separately. The generator is provided by the user.
Usually, cellphone companies have to restore service after disasters like hurricanes by sending in their own cell on wheels. But AT&T's new product would let first responders such as police and emergency workers immediately control where they have coverage.
One of AT&T's options is a unit that packs into a suitcase, with a satellite dish carried separately. The unit requires outside power, such as a generator, to work.
The Remote Mobility Zone can handle 14 simultaneous calls, and data at less-than-broadband speeds. Coverage extends up to half a mile from the unit. The "portable cell tower" can also be mounted in a car or truck.
The Remote Mobility Zone's satellite dish makes it independent of broadband service. AT&T also sells smartphones that can talk directly to satellites. The Remote Mobility Zone would be able to be used with any AT&T phone.
The cost of the units will range from $15,000 to $45,000, AT&T said, plus some monthly fees.
Like other carriers, AT&T also sells "femtocells," even smaller cellular antennas that users can place indoors. Connected to broadband service, they provide added coverage inside a home.
Structural steel adhesives proving to reduce time and tower reinforcement costs
The tower retrofitting landscape is mapped with engineered products that can assist in providing additional capacity to a communications tower - from a structural support system that will allow a compromised leg to be safely removed and replaced with a new one - to a method of encapsulating a monopole.
The newest structurally efficient entry in providing a reinforcement solution is an engineered adhesive system that was used to upgrade more than 150 cell towers in Jamaica, according to Chris Martin, Chief Technical Officer for GlenMartin, Inc. whose Boonville, Missouri-based company was awarded the challenging project.
The existing towers, designed for a wind speed of 112 miles per hour, needed to withstand Jamaica's current requirement of 150 miles per hour.
However, limitations on electrical power, terrain, labor and equipment meant the standard solution of welding and bolting were not feasible options for the time and budget restraints of the structures' owner.
“GlenMartin's challenge was how to increase the tower’s speeds from what they were actually designed for to the increased wind speed and rating,” commented Beau Aero, General Manager for GME Supply.
“Although their solution of designing specially-shaped reinforcements for the towers solved the upgrade problem, they still had to figure out how to attach the reinforcements to the towers without using welding apparatus,” Aero said.
The solution: structural adhesives
“After conferring with Martin and Aero to get a thorough understanding of the challenges, we decided that one of our high-strength structural adhesives would be the ideal solution for bonding the reinforcements to the existing structures,” explained Carlos Cruz, Market Manager for LORD Corporation, an adhesives manufacturer with products available through GME Supply.
Cruz chose a two-component acrylic adhesive designed to replace welding and other mechanical methods that is especially useful in areas subject to high-impact or high-shear loads.
According to Aero and Martin, LORD Corporation’s assistance on this project went beyond just providing a product with instructions on how to use it. They worked with GlenMartin on every step of product development and deployment, including visiting the Jamaica site several times to assure that the adhesives were properly mixed and applied.
To help create a robust tower-leg reinforcement application process, GlenMartin and LORD designed and implemented on-site surface adhesion testing and evaluation methodology, adhesive usage training, and adhesive processing and fixturing support. To help promote successful adhesive usage, they made available training and troubleshooting guides.
Ice chests were used to keep the adhesives in a controlled environment prior to dispensing. The steel reinforcements were kept in a shaded environment and bonding applications were performed earlier or later in the day when temperatures were cooler.”
Adhesives gain respectability
“Historically, in the steel structure industry, the standard for reinforcement is to use welding or fastening,” explained Martin. “Other alternatives have not been considered, and in the case of adhesives, there is the mistaken impression that adhesives are inferior to welding.”
Martin pointed out that in many other applications, replacing rivets with structural adhesives offers better structural soundness because adhesives provide continuous bonded connections unlike riveting which can only offer “spot” attachments. For the Jamaica cell tower owners, once they understood how structurally sound the adhesives were and how they were a less expensive alternative to welding, they were ‘sold,’ ” he said.
To learn more about the project and how you can successfully use structural adhesives to reinforce cell tower structures, contact Beau Aero. The adhesives and other industry products are available through GME Supply.
New online training introduced by safety advocate to allow for affordable courses
With over 40 years of experience, Gordon Lyman has chaired committees focused upon improving the telecommunication tower industry - especially in regards to worker safety.
His committees and standards groups' efforts have been well-received and the niche industry's proactive achievements have been embraced by manufacturers and contractors.
"Unfortunately," Lyman said, "an abundance of safety and technical training and standards information is available, but many companies do not take advantage of them. Budgets and scheduling in today's overheated market are preventing workers from obtaining quality training. When that happens everyone suffers."
To fill that void, Lyman has created a new online training site -SAFETYLMS - that can easily fit into any company's budget, "but more importantly," Lyman says, "they all offer the user the flexibility to train on his or her schedule and expensive travel and lodging costs will no longer be a consideration for not being able to elevate a worker's knowledge and productivity."
Current courses being offered are Fundamentals of RF Radiation, Basic Rigging Principles, Capstan Hoist Operation, and Authorized Climber. A Workplace Hazardous Materials Information System course will be released shortly and is based upon a worker’s right to know the hazardous materials they are exposed to in the workplace.
Two other courses in production are Gin Poles and Hoist.
Safety LMSystems Director of Operations Dominique Valdez notes that the company's online training offers many advantages including ease of use, a consistent message, affordability, interactive learning, and an archival system that makes retrieving copies of certificates a breeze.
"Our teaching philosophy is built upon a three-prong approach to presenting course material. This system seeks to maximize the student’s exposure to the subject matter by using a combination of visual, audio and interactive cues. Our goal is to present the information in an environment that is both informative and engaging to the user," Valdez said.
Lyman is Chairman of the NATE/OSHA Relations Committee and participates in writing ANSI 359 standards for Fall Protection in North America. He also works with industry standard groups like OSHA, ASSE, ANSI and TIA.

New process allows for inexpensive leg replacement without service interruption
Tower owners will rightfully boast about their unique services that set them apart from their competition, but they all share two common problems as their infrastructure ages: Towers that have exceeded their capacity for new tenants plus structures that are discovered to be at risk due to corroded legs, some so severe that they would ground the most intrepid tower climber.
The remedy is oftentimes an expensive tower “drop and swap” or retrofitting, dramatically affecting carrier service and severely straining the tower owner's budget.
However, TriVis Communications, a division of TriVis, Inc. located in Pelham, Ala., a national leader in industrial, commercial and utility services, has designed and successfully tested an alternative that is expected to save tower owners hundreds of thousands of dollars, and ensure a better relationship with their carrier clients.
According to Michael A. Clark, Vice President - Communications Division, his company demonstrated its revolutionary new process earlier this month whereby damaged, corroded, and structurally failing guyed tower legs can be replaced “in the air”.
Clark said, on September 2 TriVis successfully removed a tower leg from a 120-foot Rohn 80 to mock a 260-foot tower at its training facility in Pell City.
The industry-changing concept performed by members of the TriVis staff was observed by many associates within the industry, from asset owners, engineers, contractors, carriers and suppliers to fabricators, said Thom Adams, TriVis TLR's General Manager.
Through extensive research, engineering and trials, TriVis developed the flexible apparatus that provides the proper structural support to the tower to enable the compromised leg to be safely removed and replaced with a new one.
The structure maintained its plumb and tension without any loss, one of the requirements in meeting numerous industry standards
How the Tower Leg
Replacement system works
The process consists of bridging over a typical 20-foot section. Through engineered design, the unit accepts the loads above the section on a jacking system provided by Enerpac, using 60-ton jacks.
Each one is used with a 3 to 1 manifold system so that the jacks apply pressure equally. The pump is a mechanical over hydraulic. TriVis applies the apparatus on a reinforced leg with their cladding system above and below the compromised leg.
This takes the doubt out of the integrity of the leg above the compromised section. Their apparatus is designed to handle the loading of a 600-foot tower with nine carriers at 18 lines each. However, it can be engineered for any additional load. Each leg replacement will be analyzed and be site-specific.
The separation to remove the leg is minimal, typically 3/16 of an inch is needed to remove the degraded or over engineered leg. The apparatus is not limited to knock down tower sections.
TriVis can cut out welded and a bell housing flange system as well. This apparatus is designed to facilitate a simulated 20-foot section during the remediation process.
Replacement legs that are solid round members can strengthen a tower section by as much as 46%.
"In some cases engineers have completely exhausted the tower whereby no more modifications can be performed to accept the loading. Engineers are often tested to design a cost efficient design acceptable to the owner and also acceptable to the carrier to award a portion of carrier contribution finances; thereby extending the construction time frame and delaying a launch by carriers," Adams said.
Adams said that this safe cost-reduction initiative has created a great deal of interest from tower owners looking to quickly and inexpensively maintain their assets and offer additional co-location opportunities for their clients.
"This new process will extend the life of an untold number of guyed towers and self supporting towers that normally would be replaced or structurally enhanced," Adams said.

Gravitec develops rescue system specifically geared towards the tower industry
Fall protection and rescue specialist Gravitec Systems, Inc., has developed the TR System, a simple and effective rescue kit for workers at height in the tower industry.
The TR may be used for assisted rescue where the subject is lowered alone or suspended rescue where the rescuer and rescue subject are lowered together.
Ease of use, safety and versatility were Gravitec’s primary focus during the development of the TR System. Training for any rescue system is required, however, advanced, technical skill sets are not required to operate the TR, reducing the margin for human error, according to Gravitec.
If the rescuer loses control of the rope, built-in fail safes won’t allow free spooling. If the TR is used incorrectly, the lowering operation simply stops. Misuse of other rescue systems on the market may result in more serious consequences. Because the system has lifting capabilities, cutting away the rescue subject is not necessary.
This eliminates the possibility of cutting the wrong line which could result in a fall.
“The TR System doesn’t sacrifice versatility with its ease of use and fail safes. It is highly adaptable to most any rescue situation, whether it be a monopole or a rescue from the top of a tower, the TR is a very versatile rescue system,” said Gravitec Training Manager Kevin Denis.
“When a rescue situation arises, I like knowing that I have the option to choose the safest and most efficient method to rescue myself or others. The TR system includes all of the tools necessary to make that decision.”
Because Gravitec recognizes that the ability to recall training exercises may be compromised in a crisis situation when rescue is necessary, laminated cards detailing how to use the TR are included with the system. The rescuer simply attaches the cards to his/her harness with a nonload-bearing carabiner that is provided with the cards.
Simple drawings show how to anchor and load the industrial descender along with the procedures for a single-person evacuation, an assisted rescue and a suspended rescue.
“The short haul system which comes with the TR gives the end users up to a 5:1 mechanical advantage, providing more lifting power than they’ll ever need. The progress capturing device used in the short haul system allows hands free work to disconnect and prepare the rescue subject for lowering,” said Gravitec Training Coordinator William Wright.
The TR is packaged in a durable, weatherproof, PVC rope bag. A seal imprinted with each system’s unique serial number is also provided so the purchaser may seal the bag to protect the integrity of the system.
A detailed instruction manual is provided in addition to the laminated cards for quick reference.
The maximum length of rope provided with the systems is 300 feet. It may be ordered in other lengths or with fire-retardant rope if necessary.
The TR may be purchased online at www.gravitec.com or for customization of rope, contact a Gravitec equipment advisor at 800.755.8455.

Inspection program should please tower owners, inspectors and engineers
Guymast Inc. has released a new software program for tower owners, contractors and engineers that's sure to become a popular software tool for tower inspections.
With today's inspections, once the field work is completed, the inspector needs to perform calculations, create tables for a report, add photographs and a drawing for a mapping assignment.
This could easily take half a day to a day and producing the drawing could take another four hours.
With INSPECTOWER 3, the inspector will save most of that time. He can enter the data in about half an hour, and then produce drawings in less than a minute, and the inspection tables in less than a minute. Then he'll add some comments and quickly print the report.
In addition, contractors adjusting alignment and guy tensions can save at least a day of field work and a trip back to the site by using the recommended turnbuckle adjustments automatically generated by INSPECTOR 3. For additional information, visit: http://www.guymast.com/

Guying system capable of doubling monopole's capacity with a minimum increase in footprint
Structural Components’ Vertical Guy Reinforcement (VGX) is proving to be a unique solution for monopoles that have overstresses in both the pole and foundation, according to the company's vice president of sales and marketing, David Jessip.
Designed using the latest RISA 3-D software and Finite Element Analysis (FEA), the VGX has the potential to double a monopole's capacity with a minimal increase in footprint. Utilizing the same bent plate shape as the SWITCHBLADE and the BLADE, the VGX attachments fit easily onto round or sided monopoles.
The versatility of the VGX is what makes it an ideal reinforcement for overstressed poles and foundations. The attachment locations and spacing can be altered to fit around existing carriers, port holes or other obstructions.
By being able to use any three sides of the pole, the VGX will be installed so that all base terminations are within existing lease space and do not interfere with any equipment on the ground.
The base termination of the VGX is custom designed to site-specific geological conditions. Whether the ground is soft sand or hard granite, Structural Components will custom design base terminations that will ensure the stress is taken out of the existing foundation.
