Dish Network receivers, switches and LNB’s use DISH Pro technology that utilizes bandstacking which combines both the odd and even signals on one coaxial cable. The odd transponders are in the frequency range of 950 to 1450 MHz, while the even transponders are in the 1650 to 2150 MHz range. Because the frequencies are different, the signals will not interfere with each other. This means that bandstacking simplifies installations by using only one cable per satellite location to an external switch. The DISH Pro DP34 switch needs only one cable from each satellite location. This means that only one cable from each of the three satellite locations need to be connected to the three inputs on the DISH Pro 34 switch.
