Details
QUATRO LNB is a converter with four independent outputs: 10.7 - 11.7GHz band with vertical polarization, 10.7 - 11.7 GHz band with horizontal polarization, 11.7 - 12.7 GHz band with vertical polarization, and 11.7 - 12.75G Hz band with horizontal polarization. QUATRO converters are used in installations built with multiswitches and TV head stations, where they cooperate with sets of satellite receivers. They are also employed in installations providing the first satellite intermediate frequency. More about satellite converters can be read here.
