WHAT'S INCLUDED - 4x DIRECTV DECA Ethernet-to-Coax adapters - 4x AC power supplies - NOT included: coax cables, Ethernet cables, splitters, PoE filter HOW IT WORKS Each adapter bridges an Ethernet connection onto your existing coax line. Connect one to your router and the others at any coax outlet in the house. Minimum of two units required — this is a point-to-point system. IMPORTANT COMPATIBILITY NOTES — PLEASE READ BEFORE BUYING - These units communicate with OTHER DECA units. They are not designed to interoperate with standard third-party MoCA 2.0 adapters. - Your coax splitters must pass the required frequency range. Standard cable splitters may block the signal. This is the most common setup issue. - If you also have cable internet on the same coax, a PoE (point of entry) filter is recommended.
