Cable Signal Leakage Detector

Cable operators are considered secondary users of these frequencies.

Cable signal leakage detector.

But just what is field strength. After a fairly quick inspection he found a place where the cable was stapled to a floor joist too tightly compressing the cable which changes the properties of the shielding and causes it to radiate signal. Cable signal leakage can interfere with any of the over the air services using the same frequencies as the cable operator within the vicinity of the cable system. About 25 years or so ago a cable tech stopped by my parents house saying that there was cable signal leakage.

Using a dedicated leakage detector typically with a built in antenna orient the detector and its antenna to get a maximum reading and see. Cable leakage technologies 1211 executive drive e richardson tx 75081. As it turns out comcast had detected some sort of signal leakage inside my home that was caused by unused open cable outlets. The measurement of signal leakage is fairly straightforward.

In the home coaxial network signal levels are lower than outside plant levels and the migration to all digital services means even greater sensitivity is needed in a leak detector. The signal cable should be terminated between the sensor and the main alarm bms in the following manner. Cable signal leaks can be caused by loose connectors damaged plant cables or cracked or unterminated cables. Cable systems use broadcast tv radio aeronautical radio federal aviation administration and other channels.

Connection to signal cable signal cable wire colour vdc ac red 0vdc ac blue contact n o yellow contact n o black stainless steel fixing bracket pvc housing optical sensor 21 5mm thread 3m long signalcable signal cable. However unlike fluid leakage cable signal leakage is invisible and therefore more difficult to pinpoint the source of the leak. Given this constraint a signal leak from one location can potentially mask a leak from a nearby location. Cable operators for decades have dealt with the monitoring and measurement of signal leakage field strength.

Cable signal leakage cable signal leakage sometimes called egress occurs when rf signals leak out from the cable plant and spread into the environment. Contact us at 972 907 8100 in richardson tx for our rf detector services to find the signal leakage in your cable cable. Signal leaks can also be intermittent meaning a slight bend or movement in the cable from one point in time.
