Description

ETS-Lindgren’s Tuners are made of large aluminum reflecting sheets supported on either a rigid box (truss) frame or a single spine and designed to provide the efficient reflecting surfaces necessary for use in a RF reverberation chamber.

Reverb chamber tuners are available as separate assemblies for retrofitting to existing shielded facilities. The Tuners are supplied with matched motor drives capable of up to 16 RPM for use in continuous rotation mode or with down to 0.1 degree resolution for use in tuned mode.

Most shielded rooms can be converted to Reverb chambers with the installation of one or more suitably sized automatically controlled tuners. The chamber should ideally have dimensions, which are not integer multiples of each other to reduce mode degeneracy and be large enough to support multiple modes.
