Abstract

A method and apparatus for coupling a system propagating wireless home networking communication signals to a system propagating television signals over a coaxial cable system to a device capable of receiving television signals that includes a three-port adapter having an antenna port, a first coaxial cable port and a second coaxial cable port. The antenna port is coupled to the system propagating home networking communications signals. The first coaxial cable port is coupled to the system propagating television signals over a coaxial cable. The second coaxial cable port is coupled to a device capable of receiving television signals.
