The device is processed mediocre and does not come with any instructions. The technical data can be - only to guess at the appropriate frequency range. Unfortunately, the device has in no way served its purpose. A gain of the signal was not detectable. After connecting the amplifier the TV picture (tube 70cm and 55cm tube) was no longer visible. (Correct connection guaranteed) Maybe it is not suitable for the digital cable network, but that is not to determine, as appropriate instructions are missing. Recommendation: Better to buy a higher quality brand device that has been expressly released for digital cable TV.
