Anechoic RF Chamber

The NRAO Green Bank, WV site contains an anechoic chamber in the Jansky Laboratory Annex Building.  This chamber mimics free space by absorbing electromagnetic waves and electromagnetically shielding the room from outside sources. For these reasons, this room is extremely useful in measuring an antenna's directional pattern.  The room is 27'x15'x15' with walls covered with 8" and 6" pyramidal absorbers.  The chamber is designed to work in the range of 2-50 GHz and 60-115 GHz with a dynamic range of about 60 dB.  The antenna under test (AUT) and the source antenna are located on stable towers 7.5' above the floor.  These towers can support AUTs up to 350 pounds.  Contact the TTO for more information.
