This inexpensive satellite meter works with all analogue and digital satellites and gives an audible tone and needle deflection when it detects a signal. It can be used with the signal meter that's built-in to your Sky Digibox or Freesat receiver indicate whether you have the correct satellite (the meter itself will not discriminate between different satellites).
The meter comes with a flylead to connect from the LNB at the dish to the meter input.
