 Such an attenuator can easily be built from three SMD resistors. Alternatively, the connection cable can be separated and the inner conductors left at a distance of 1 cm from each other. The exact value of the damping is irrelevant. Such an attenuator can easily be built from three SMD resistors.

 +this attenuator has just under 40dB and deliberately no match to 50 ohms, because the focus here is on safety in case of accidental transmission, which would not be guaranteed with a 50-ohm attenuator.
