Eccosorb™ RF-RET Broadband Foam Absorbers

Laird Eccosorb™ RF-RET Broadband Foam Absorbers are lightweight, open-celled, reticulated foam absorbers with 20dB performance ratings. The defined cell structure is formed by the reticulated urethane backbone, and when treated with a lossy coating, the material is extremely lightweight, providing broadband reflectivity reduction. Laird RF-RET absorbers are used for antenna reflection reduction, where broadband reduction is required alongside a lightweight design. Laird Eccosorb RF-RET Broadband Foam Absorbers are useful in anechoic chambers to cover pedestals and equipment.
