installed Hitron Bonded MoCA 2.5 Adapter for Ethernet Over Coax (2-Pack), connecting AT&T residential gateway to Apple TV one floor below. Working fine, but literature indicates many benefits of having a MoCA POE filter in place. Such filters connect at the point of the incoming coax drop. However, my incoming line (AT&T) is twisted pair going directly from the street into the gateway. Where would I place a MoCA filter in this scenario?
