FAQ 193-2002-en

In an installation with 2 dishes for analogue satellite TV (or with a single dish with a multifeed system) with:

  • One coaxial downlead
  • The use of ref. 7432 tone switch.

I have the following problem:

  1. I only receive one satellite signal.
  2. The other dish receives a few channels or channels with a high level of noise.

 

Respuesta: 

In this kind of installation, with universal LNBs, the 22 KHz tone sent by the receiver causes the tone switch to select one of the dishes.

This tone passes through the switch and then enters the LNB, changing its output to the high band.

This band is usually used for digital transmissions.

The solution is to:

Change one of the universal LNBs (the one affected by the tone) for a non-universal LNB.
