Which demodulator for a motorized satellite dish?

Hello,
A few years ago, we installed a motorized stereo satellite receiver SL 1 M.
Today the receiver is not working well and I won’t even talk about the remote control. My dish is stuck to the east, where of course there are no channels; Can someone tell me what type of decoder I can buy so that it will be compatible with my motorized dish?
Thank you.
Configuration: Windows XP Internet Explorer 6.0

    Wiring with coaxial only. From the LNB to the motor and from the motor to the receiver or switch.

    I am thinking about buying a Diseqc 1.2 motor. I saw some for around 50 euros!!

    I carefully read your comments because I have the same problem, but your responses for a novice are a bit like those of a surgeon.
    In the end, we didn't understand anything about what we had and we don't know if there's a solution.
    I did understand that the antenna will not be controlled by a new demodulator that commands via coaxial, but can we control it with the old demodulator and decode with a new one?
    Thank you.

      Thank you for this information, but do I necessarily have to change my decoder in order to orient my satellite dish? My remote control is almost broken; I can no longer use it to move my stuck dish.
      Thank you for your reply.

      The satellite antenna + SL1M motor (analog) has a motorized control via an external cable with RJ11 plugs.
      How can we keep the satellite antenna + motor if we want to change the decoder?
      Everything now seems to go through the coaxial cable.
      That’s a good question!

    Digital demodulator featuring the universal standard DiSEqC 1.2 for DiSEqC 1.2 motorization, for example, Stab rotor.

    Apart from Fransat terminals, BIS TV, Via Eutelsat (using the DiSEqC 1.2 protocol), and the many others from independent private manufacturers, one should not imagine for a second being able to control motorization with a location terminal, like Canalsat, not even with a TNTsat..!!!

      Is there an adapter that connects to a digital or analog terminal to control the motor (currently connected via RJ11)?
      I'm thinking of a box with one side coax to demodulator and on the other two outputs: one coax (LNB) + RJ11 to control the motor.
      Otherwise, I would have to change the motor and demodulator, which would be expensive!!! And I'm not a seller of antennas :-).

        The Stab antenna rotor is controllable via the antenna coaxial cable from any Diseqc 1.2 terminal (e.g. Fransat); it's standard, all the rest is obsolete and no longer commercially supported in France.

        Have you found a solution? Because I have the same problem, a terminal (a Cherokee 9100) with DiSEqC 1.2 and a DiSEqC 1.0 motor (SL 1M).
        My solution is to keep the analog terminal to control the motor, but if you have a better one, I’m interested.

    Hello,
    the analog kit with a motorized satellite dish (motor controlled via an external cable) is still working well. The only downside is that the analog channels are dwindling fast and soon we won't have a choice. It's either digital or nothing, and even though everything is functioning, it will all need to be replaced (great, the consumer society!!).
    I thought I could just change the demodulator, but it seems that's more complicated with an external motor control instead of via the coax.

    With a DiSEqC 1.2 motor, how does the relationship between the LNB and the motor work?
    I suppose the whole system forms a block (connection to the motor or vice versa and internal wiring between the motor and LNB).
    I don't know.

    Hello

    The normalized relationship between the LNB head, the rotor (Stab Technisat, etc.) Diseqc 1.2, and the satellite decoder (digital or analog) Diseqc 1.2 or Diseqc 1.3, is established by the only coaxial cable that carries all the control impulses and the 2 voltages. It's the same for a motor type actuator, Diseqc 1.2, which is usually used for antennas > 1.20 m, especially for C band applications.

    Wired systems with 4 or 5 electrical cables + coaxial cable are obsolete in Europe, as is the antenna positioner.
