Abstract
A system for broadcasting a telecommunications signal is configured to detect the use of an improper filter, and/or also, the presence of an improper return signal from a filter. The system includes a broadcast cell having a signal generation component and a signal transmitting component, a filter through which the signal generated by the signal generation component is sent, and a directional coupler that diverts a portion of a return signal reflected from the filter back to the broadcast cell away from the broadcast cell to a detector, the detector configured to determine when the return signal is at least a minimum level, or within a range, that indicates use of an improper filter or the presence of an improper return signal, allowing modification of the system or notification of the conditions, in certain circumstances.
