  • Cable Signal Leakage. Testing Signal Leakage. LTE Interference

    Signal leakage refers to the loss or egress of radio frequency (RF) signals from a cable system when they are not properly contained. This can result from a multitude of causes but is generally the result of shielding defects within the cable network. In the US, FCC standards for signal leakage encompass egress from both analog and digital cable systems.
