Bypassing an Amplifier

To bypass the MoCA signal around an in-line amplifier that cannot handle two-way traffic nor has insufficient bandwidth for MoCA:

1.Locate the line amplifier by tracing the coaxial cable back towards the ONT.

2.Disconnect the existing RF cable from the amplifier.

3.Move the existing amplifier to a position near the point of entry.

As shown in the figure below, connect each existing coaxial cable to the diplexer. Connect a new coaxial cable between the high pass ports on the diplexers. Connect the existing amplifier between the low pass ports on the diplexers.

Install straight Coax
