DishPro LNBFs are a new technology that is only supported in the newest receivers from Dish Network (Models 301, 501, 508, and 721). DishPro LNBFs and switches allow for longer runs up to 200 feet from receivers to the dish. DishPro installations are easier as there are fewer cables to run from the dish  to the switch(es) for more than 2 receivers as well as simpler installations if more than 4 satellite feeds are needed (especially important now that 721s and 921s need 2 satellite feeds per receiver).

DishPro is different as it will stack or transmit both even and odd signals down the same wire, by shifting the frequencies up so both polarities can travel the same feed to the receiver or switch. Since this is the case the LNBF doesn't need the receiver voltage to switch back and forth. A switch is necessary to be able to connect one stacked 119º feed and one stacked 110º feed to each receiver. The only way a legacy receiver will work with this arrangement of LNBFs and DishPro switches is with a DishPro adapter that can down convert the stacked frequencies to the standard odd or even only frequencies. Each legacy receiver has to use this adapter which must be installed within 10 feet of the receiver.
