Abstract
The present invention utilizes a coupling tap that contains two parallel communication paths from the connection at a coaxial cable to a tap output, to which a device can be connected. One path passes high frequency signals of 30-900 megahertz, while the other passes lower frequency communication signals of 0-5 megahertz as well as DC power. Furthermore, each tap may contain a line isolating inductor that, when a particular tap is in use, isolates the portion of the coaxial cable that continues on past the tap in use for signals from 0-5 megahertz. This eliminates reflections and other line disturbances from entering the tap in use.
