The Amplifier Bypass kit routes the tvLINK signal around an old style existing UHF amplifier.
Fully compatible with the Sky digital tvLINK System, the Bypass Kit allows the tvLINK return signal to route around another manufacturers distribution amplifier. This is necessary when the original amplifier cannot be replaced.
The Global Bypass Kit is designed to carry one tvLINK signal only. They cannot be cascaded. To accomodate more than one tvLINK the existing amplifier would need to be replaced with a Global Distribution Amplifier.
