This Channel Master CM6001 adapter
is used to help you get internet from point A to point B over a coax line. If that sounds like DIRECTV's DECA technology, there's a reason: both are what's called MoCA adapters. MoCA is the group that designed the standard for sending internet information smoothly over a coax cable, but they left the standard a little loose.
Channel Master uses one set of frequencies for their signal, Verizon a different one, DISH a different one and DIRECTV yet another. So you really can't use them interchangeably, unfortunately.
What's more, if you connect a MoCA adapter from another manufacturer to a DIRECTV system you run a pretty good chance of disrupting the satellite signal. So if you have a DIRECTV system you're much better off using the DECA devices DIRECTV makes for its receivers
, even if you're using them to run non-DIRECTV equipment.
