Frankonia’s compact hybrid chamber solution at 3.0 m measuring distance
The CHC is Frankonia’s optimal solution for both pre-compliance emission tests and full compliance immunity tests at 3.0 m measuring distance. The most important advantage of the CHC is the upgradability from semi-anechoic chamber with ground plane to fully anechoic chamber with absorbers on the ground.
