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. > SPECIFICATIONSTD-500 COFDM DVB-T COMBINATOR / DISTRIBUTOR COFDMFrequency range 45 MHz to 875 MHz Total insertion losses From 45 MHz to 50 MHz6.9 dB (typical), 7,3 dB (max.)From 50 MHz to 450 MHz7.3 dB (typical), 8,1 dB (max.)From 450 MHz to 900 MHz8.1 dB (typical), 9,3 dB (max.)
