PCT makes one that is MOCA compliant on active ports, does not work on the passive EMTA port. However they make another that MOCA works across all ports so verify which one you need.
Sorry did not pay attention to the two gang part. You can use one of their one port amps to boost incoming signal. Any of their splitters as most are MOCA compatible so long as they pass over 1ghz. Dont forget your moca filter on the input side of root splitter to help overcome port to port isolation of splitter legs.
