4.2.2. Amplifier without switchable return path
If it is not possible to switch off the return path, two high-pass filters TZU 19-68X must be installed at the
output of the amplifier.
Important: The use of the high pass filters TZU 19-68X is mandatory in order to achieve sufficient
blocking depth for the frequency range of 5...204 MHz. Otherwise it may cause interferences in the
cable network.
