Use one sky controller to control two polar axis antennas

First, make a control circuit, see the attached figure, and then set up the aerial controller and receiver.

The control circuit consists of relays J1, J2 and rectifier diodes D1, D2. The relay coil voltage is required to be 12V, with two sets of normally open and normally closed contacts. The relay contact capacity used to switch the electric push rod power line should meet DC24V10An. When receiving C-band programs, set the "12V output" option in the receiver antenna menu to "off", and set it to "on" when receiving Ku-band programs. At the same time, set the 22KHz or DisEqC option according to the selected antenna switch. When watching C-band programs, the receiver's 0/12V terminal has no 12V output, and J1 and J2 do not operate. The sensor signal input terminals S1 and S2 on the rear panel of the antenna controller and the electric push rod motor power output terminals M1 and M2 are connected to the corresponding ports of the C-band antenna electric push rod through the normally closed contacts M1 and M2, respectively. At this time, operating the antenna controller will activate the C-band polarized antenna. When watching Ku-band programs, the receiver's 0/12V terminal outputs 12V voltage, J1 and J2 are attracted, and the four wires between the antenna controller and the Ku-band polarized antenna electric push rod are automatically switched and connected. At this time, operating the antenna controller will cause the Ku-band polarized antenna to rotate. This achieves the purpose of controlling two sets of polarized antennas with one antenna controller.

It's important to note that when using a dual-LO tuner for Ku-band reception, the receiver's 22 kHz pulse signal is used to switch between the Ku-band tuner's high and low frequency bands. The DisEqC switch should be used to switch between the C- and Ku-band tuners. Early-generation satellite controllers capable of positioning 32 satellites may be adequate for receiving some valuable satellites today, but for long-term development, a controller capable of storing 100 satellite positions should be selected.
