The TD-500 is a general purpose DVB-T combinator and distributor to be assembled in a 19-inches 1U-height rack. The equipment, in its basic configuration, has two identical internal modules including 4 inputs and 1 output or 1 input and 4 outputs. Anyone of these modules can be used as combinator or distributor.
The equipment can be delivered with different configurations and offers up to 4 combinator/distributor modules with 2 and 4 inputs (refer to PROMAX for availability). Each one of these modules is bi-directional, being those of 2 input/output that which offers less loss.
The basic TD-500 can combine 4 RF signals coming from 4 modulators, as the MO-170, and to distribute the combined RF signal to 4 distribution lines.
