the regulator has two Supply Input pins VCC1 and Intended for analog and digital satellite receivers, VCC2.
They must be powered respectively at 16V the LNBK20D2 is a monolithic linear voltage (min) and 23V (min), and an internal switch regulator, assembled in SO-20, specifically automatically will select the suitable supply pin designed to provide the powering voltages and the according to the selected output voltage.
If interfacing signals to the LNB downconverter adequate heatsink is provided and higher power situated in the antenna via the coaxial cable.
