Bandstacking (950-2150 MHz) - When connecting an LNBF to a switch, our current system uses one cable for 13 volts and the other cable for 18 volts to access the odd and even transponders, respectively, in the frequency range of 950 to 1450 Mhz. Bandstacking combines the signals onto a single cable. The odd transponders are accessed in the frequency range of 950 to 1450 Mhz, while the even transponders are accessed in the frequency range of 1650 to 2150 Mhz. Therefore, bandstacking simplifies installations by using only one cable per orbital location to an external switch.
