1. An instrument for determining leakage at a subscriber's premises in a cable television (CATV) network, the instrument comprising:
an antenna that receives (i) a first test signal having a first frequency in a first band and a first signal level and (ii) a second test signal having a second frequency in an Long Term Evolution (LTE) band and a second signal level, the first and second test signals being radiated from at least one oscillator connected to the subscriber's premises CATV network for determining a leak in cable wiring at the subscriber's premises, wherein the first and second signal levels are each 40 dB to 70 dB above a third signal level of a cable signal supplied by the CATV network to provide a high power offset between the first and second signal levels and the third signal level, and the third signal level is in a range of −5 dBmV to 0 dBmV; and
a signal level meter electrically coupled to the antenna to receive the first and second test signals from the antenna, the signal level meter being configured to measure the first signal level of the first test signal and the second signal level of the second test signal and to generate an output signal to cause a graphical indication of the measured first and second signal levels to be presented on a display, wherein the graphical indication includes a field strength of at least one of the first and second test signals,
wherein the instrument is portable to be transported around the subscriber's premises to locate the leak.
