Here is my C-Band parabolic tv digital receiver. As shown by the pictures, the incoming coax cable (INPUT) connected both the outer and the core. One goes to digital receiver 1 (receiver 1), and another goes to digital receiver 2 (receiver 2).

  • If BOTH receivers are turned ON, they are working fine.
  • If receiver 1 is turned OFF, receiver 2 is working fine.
  • But, if receiver 2 is turned OFF, the receiver 1 is NOT working.

They are supposed to be connected by a spliter. Unfortunately, I don't have a suitable one. This is temporary until I get it. Then my question is, why is the receiver 1 can not be independent from digital receiver 2 (but not vice versa)? Which one is better in term of loss affected by the connection compared to if compared to use combiner?

  • $\begingroup$ Is receiver 1 plugged into the back of receiver 2 for power? $\endgroup$

  • $\begingroup$ No, it is not. You can see the cabling. They are separated as it is using spliter. $\endgroup$

  • $\begingroup$ I was asking about the power cord. Some boxes like that have a switched outlet on the back, without it being marked as switched. $\endgroup$

    $\begingroup$ I'm voting to close this question as off-topic because OP manually twists together coax cores and mantles, knowing that only a splitter can properly fulfill the role of splitting signals, and hopes to get an explanation why things behave erratically and unpredictably: Obviously, erratically and unpredictably just twisting cores and mantles together leads to erratic and unpredictable results. There's nothing to be answered here! $\endgroup$ Aug 5, 2019 at 12:29
