The Seeker D Lite Shielding Integrity Testing Kit gives technicians the ability to verify whether cellular devices have the potential to cause harmful interference with advanced in-home services such as high-speed Internet, TV and phone. It is designed for use in both the Aeronautic and LTE bands and offers sensitivity as low as 0.1 uV/m. The small size and built-in antenna allow technicians to move through confined spaces in the home. The three-button design, dual band display, and tone proportional to signal strength reduce the time it takes for technicians to become familiar with the device, Trilithic says.
