An apparatus includes an RF input configured to receive RF signals from a communication network subscriber site. The apparatus includes a signal processor operably coupled to the RF input. The signal processor is operable to scan the RF signals for power levels at a plurality of frequencies and generate power level signals based at least in part on the power levels. The apparatus includes a controller operably coupled to the signal processor. The controller is operable, in response to at least one user input command, to cause the signal processor to scan the RF signals for the power levels with the plurality of frequencies spread over at least one predetermined frequency band. At least one of the controller and the signal processor is operable to indicate an ingress susceptibility of the subscriber site in at least one human-perceptible form based at least in part on the power level signals.
