Abstract
Apparatus and methods for the management of radio frequency spectrum within a network such as a CATV network. In one aspect of the invention, an improved signal reflector apparatus adapted for use in the network is disclosed, the reflector circuit being designed to strongly reflect signal frequencies at the lower end of the CATV reverse band, and/or above the higher end of the forward band, while simultaneously allowing the rest of the reverse band and the entire forward band to pass freely through the device. This selective filtering of the spectrum allows control signals generated within a premises or private network to be directed (by reflection) to other devices within that network. A blocking element (e.g., amplifier) may also be used to provide control of the transmission and attenuation profile of the reflector apparatus. The passage of power signals such as DC or low frequency AC is also optionally provided.
