boas, já alguém experimentou este switch?pelas reviews parece ser possível atraves de um dual lnb que eu já tenho, colocar para 4 receptores sem o problema dos verticais/horizontais.3 X 4 Digital Satellite MultiSwitch & CombinerSmall enough to fit in the palm of your hand, smaller than a pack of cigarettes, but BIG enough to power up to 4 satellite receivers. Convenient size makes working within an enclosure a snap! Powered by satellite receivers. No external power source needed. Compatible with all 18-inch round satellite dish antennas with dual lnb's. You will not find a lower price for this DirecTV 3X4 multiswitch anywhere! ~ DirecTV[SUP]®[/SUP] APPROVED!
