AM Detuning Systems require RF awarness
AM Detuning Systems require RF awareness

In response to customer requests, the LBA RF Safety Awareness course for wireless workers has been updated to include a new section on AM detuning hazards. The new edition also includes revisions to other sections.

Byron Johnson, course administrator said “We encourage feedback from our users, and strive to make our RF safety courses totally relevant to the evolving certification needs of the wireless infrastructure industry.” Earlier, a Spanish language edition of the RF Awareness course was release to ensure that primarily Spanish speaking workers in the US and abroad were properly trained. Since its inception, a management feature has also been added to facilitate safety managers’ recordkeeping and tracking of personnel certifications.

AM detuning has become a safety concern as the number of detuned towers has increased in the wireless ecosystem. Detuning is performed when a wireless tower is located near an AM broadcast tower. It consists of rigging the tower with a cage of wires and a tuning box to neutralize the impact of the tower on the AM station. Significant energy can be coupled from the AM station, making the detuning cage wires “hot” with RF. Rarely sufficient to cause direct injury, the AM RF can cause shock and burn startle responses and precipitate secondary injuries. The course now prepares workers to recognize and manage these exposures.

Byron reminds the hundreds of past certified persons that refresher training is recommended annually. A special “reup” credit is available for those re-certifying.
