C-RAM: SFC-HC

High Power Honeycomb Pyramidal Absorber

PPG C-RAM® SFC-HC is a series of high power pyramidal absorbers made from specially treated plastic honeycomb. Using a pyramidal design, which provides an impedance gradient, PPG C-RAM SFC-HC provides premium performance in anechoic chambers at both normal and off-normal incidence angles.

Standard sizes of PPG C-RAM® SFC-HC are listed in Table 1, ranging from a 3¼ inch to 24 inch height. PPG C-RAM SFC-HC-3 up through SFC-HC-24 are shaped as conventional pyramids and supplied as square 24 inch (610 mm) panels.

In addition to simply supplying a bill of materials, Cuming Microwave designs and installs complete anechoic chambers. Chambers can be designed to meet your specifications, and an entire kit of materials is supplied, including factory pre-cuts of special fitting parts. We can install all materials or supply technical support to help you complete your own installation.

Custom sizes 48 in. to 72 in. in height are made in two or three sections held together with a couple of polymer threaded rods 1/8 in. dia., using polymer washer and nuts.
