DISH PRO technology is used by DISH NETWORK. All Dish Network receivers since early 2002 are DISH PRO ready. The DISH PRO technology uses a 1 Ghz bandwidth at 950 to 1950 Mhz to transfer the satellite signal from the LNBF to the receiver. The LNBF voltage is fixed at 19 VDC. DISH PRO uses DiSEeqC controls to communicate with the LNBF for multi-satellite selection. DISH PRO compatible receivers will also work with standard LNBS. Adapters are available to convert DISH PRO signals to standard signals for incorporating non DISH PRO compatible receivers into a DISH PRO system.
