Telecom and broadcast workers who climb towers and may be exposed to RF energy can wear this device that will warn them if they are being exposed to RF radiation. In engineering the assembly for Narda Microwave, we first created an internal container that is easy to manufacture and met the rigid specifications set by their scientists. We then created the outside assembly, integrating the two parts seamlessly. We also developed a unique second clip for the pocket for the comfort of the user. The shape is contoured to fit to the body. It was rated as one of the best 100 new products of the year by R&D Magazine.
