I run this amp on a cable connection from KMS. The reception of HD channels ARD and ZDF is unstable in the living room without the amplifier. To the amplifier is no problem. The TV was previously at a terminal of Unitymedia until we moved. KMS used in the main channels an identical channel assignment, probably because a few years ago, the landlord ABG has passed the cable TV of Unitiy Media at KMS in the property and should run the conversion for the tenants without channel search. Anyway, I now have found no problems with the amplifier up, all public and private radio channels that I look so, still operate. The apartment has an outstanding DVB-T reception, which means that in poorly shielded antenna cables scatters the DVB-T TV and interferes with the HD channels of ARD and ZDF. You must use a Class-A antenna cable, so a cable with increased shielding (90Db have cable in use). In this respect there is no problem with the amplifier.
