The SOC-4 adder sums up the signal from the Quad converter with the terrestrial TV signal (internal). It allows to send the aggregated signal to 4 independent recipients. To distribute the signal at the end, an RTV/SAT end socket should be used, e.g.: DSE S1-1-T
| TV frequency range | 47 - 862 MHz |
| SAT frequency range | 950 - 2150 MHz |
| TV signal attenuation | 9 dB |
| SAT signal attenuation | 2 dB |
