Remember that the STB stuffs about 20v down the Coax to drive the LNB. This is
enough to give you an electric shock.

Is this from direct experience or are you perpetuating an urban myth
here?

Even with upwards of 50 volts I have never even felt a tingle

a couple of kV from the output of a central heating spark transformer,
now that wakes you up
