The GT24W module is part of the Tangram product portfolio. The GT24W module allows you to add up to 8 channels in COFDM (DVB-T) format per module to your network. Tangram is a very high density and highly flexible solution for all kinds of networks. The WISI Tangram chassis uses a fully redundant concept (n+1, 1+1).
