Featured Products & Solutions3M One Step Closure for Wireless The OSCW closure from 3M is used at two main connection points—the smaller OSCW-S is used at the antenna and the larger OSCW-L is used at the feeder to jumper cable.
These connection points can be the sources of many problems for tower cellular operators. Moisture can intrude into the coaxial cable where the DIN and/or N-type connectors are used. The large core coaxial cable can be adversely affected by the elements, which can lead to signal integrity issues. Sealing gel surrounding edges of closure Reusable, One-piece design Easy to close latch—no tools needed.
Tier 1 Carriers Respond to Rising Theft Facing the prospect of being unable to secure copper bars on cell sites, several Tier 1 Carriers have begun specifying Galvanized Steel Bars as a way to keep some level of protection.
Galvanized Steel Bars simply are not an attractive target for thieves. While copper is still the best solution for conductivity, having a Galvanized Steel Bar at the site significantly reduces the likelihood that your site will be left unprotected.
Get FCC Compliant With TESSCO's Complete Back-Up Power Solutions The most common sites can be sorted into three categories based on total site power consumption. Each site kit would include the correct combination of rectifiers, chargers, battery capacity, generator switches and rack systems to keep the sites up and running for a minimum of 8 hours required by the FCC.
Featured NewsNational Two Man Tower Rule is on FAA's Agenda, but It's Too Late for 59-Year-Old WorkerArticle courtesy of Wireless Estimator June 2, 2009 — The need to create a national fall protection standard for the Federal Aviation Administration for employees working on towers has been a concern for a number of months.  It is expected to draw renewed attention at the FAA's Southern Region Occupational Safety, Health, and Environmental Compliance Committee scheduled for June 10 following the death of an employee who fell from a tower on May 29 while working alone without any safety equipment at the Palm Beach International Airport.
The deceased worker, 59-year-old Ismael Octtavanni-Mercado of West Palm Beach, who had fallen off a decommissioned 60-foot radar tower site a number of hours before being found, was not involved in installing or maintaining any communications equipment, according to an Atlanta FAA spokesperson. At the FAA regional meeting on February 25, Engineering Services Representative Steve Hardee gave a draft presentation about requiring two people for all climbs. They would be required to be First Aid and CPR trained, and that one be rescue trained for climbs that are off the safety ladder system and on towers over 100 feet tall. The committee recommended that both climbers be rescue trained. It was also recommended at the FAA meeting that the "corporate impacts regarding staffing this requirement" be discussed with comptrollers. "For safety reasons, NATE has long been an advocate of having a minimum of two tower climbers on site for all projects," said National Association of Tower Erectors Chairman Jim Coleman, upon learning of Octtavanni-Mercado's death Friday and the FAA's desire to provide a safe environment for their technicians required to work on towers. "Beyond that, the association has been working with the Occupational Safety and Health Administration for a number of years on the creation of a federal tower safety standard. The most recent example of such a standard has been established by the State of Michigan. This standard makes it clear that two workers should be on each site and also includes realistic examples of how the rescue component of a safety standard should be addressed," Coleman said. Michigan And North Carolina Could Provide a Starting TemplateThe FAA committee could take advantage of the extensive research and promulgation efforts of NATE and members of Michigan's and North Carolina's state occupational safety and health organizations. Effective in April, Michigan's new communications tower standard addresses a requirement ensuring that at least two rescue-trained employees are on site when employees are working at heights over six feet on the structure. When there are only two employees on site and one of the employees has been employed for less than 12 months, then the new employee must minimally have documented rescue training which includes steps to be taken in an emergency. North Carolina's 2005 fall protection standard requires that at least two trained and designated rescue employees must be on site when employees are working at heights over six feet on the tower, provided however, where there are only two employees on site, then an employer may comply with the requirements of the standard if one employee is a trained and designated rescue employee and one employee has been designated by the employer as a probationary employee and has been employed for less than nine months.
