Laird Technologies Eccosorb RF-RET Series Broadband Foam Absorber

Laird Technologies Eccosorb RF-RET Broadband Foam Absorbers are lightweight, open-celled foam solutions designed for superior performance and have a 20dB rating. The specialized cell structure, crafted from a reticulated urethane backbone and enhanced with a lossy coating, ensures minimal reflectivity while remaining incredibly light. These RF-RET absorbers are ideal for reducing antenna reflections, making them perfect for applications where both broad-spectrum performance and lightweight design are essential. They are also highly effective in anechoic chambers, providing optimal coverage for pedestals and equipment.
