Sonora Dual DIRECTV^® DStacker for TiVo Receivers (D575D)

Single line distribution is the combining of both polarities of DBS on a single drop cable. Terrestrial signals from 50 to 800 MHz may also share the same drop cable. Stacked DBS signals contain the odd polarity from 950 to 1450 MHz and the even polarity from 1525 to 2025 MHz. Model D575d diplexes the terrestrial signal to the TV and provides (2) independent DBS outputs. Satellite switching signals (22 kHz) pass from tuner B to enable recording from other satellites. A dual tuner receiver TiVo can operate each tuner independently from only a single drop cable. Unit ships with mini-coax cables for easy connection to the recorder.
