            The D1201294 contains a mini-circuits ZFL-500LNB+ which it drives with a -12dB coupler, and then splits to 2 outputs.  The ZFL gives 28dB of gain, and the attenuation is normally 15dB, 12 before and 3 after the ZFL.  I connected the input directly to the ZFL and used the directional coupler to produce 2 outputs; one with +27dB gain and the other with +15dB.
