LONG HOLLOW ABSORBER WITH FRAME
With size increasing, the standard SA type absorber becomes heavier which in turn presents its own challengers in regards to both fixing the absorber (to the ceiling and walls) as well as absorber tips drooping due to their overall length.
The SAH/CAH, hollow pyramid absorber replaces theSA type, for all absorbers greater than 1.2m in length. They are combination of multiple absorbing parts.
SAH is a polyurethane pyramidal tip and outer layer, lined over a hard-polystyrene pyramid frame.SAH reflectivity performance is as good as the SA and also works down as low as 30 MHz.
CAH is only the polystyrene foam with wave absorbing film and is primarily used in EMC enclosures.
