In these cables the attenuation is given priority with regard to noise. (Z. B. 120 dB) That was interesting for me because I had no interference effects even with a simple shielded cable. Only today I have seen that the attenuation of the useful signal has been given. She is in the interesting range of 1000 to 2000 MHz (frequency dependent) 17 to 27 dB per 100m. This means that only about half of the signal voltage of the multiswitch arrives in my case on television. In my experience that is rich. In the future I will include but this attenuation in my purchase decision.
