Using a cable tester, which can tell you where the cable travels if you have a few cables that are linked to different devices and run to several places around your house, will save you time and money in the long run.

Such devices include a “sending” function, which allows them to transmit a specific signal that travels via the cable to the recipient. The procedure is very straightforward:

  • Connect the transmitter device to a jack on the receiver device.
  • Each cable should be tested using a speaker module.
  • After you have connected the correct cable, you will hear a tone. That is how simple it is.
  • Locate the cable and determine when the other end is accessible.

If you have a large number of cables that transmit signals to a large number of devices and you need to locate the appropriate cable, you must follow a straightforward procedure.

The following tools will be required: a multimeter and aluminum foil.

  • Insert a piece of foil into the jack of a cable.
  • With the multimeter, check all of the cables (it reads ohms)

The “0” will be shown on the cable that was shorted out by the piece of aluminum foil.

Experts, on the other hand, say that although various results may be obtained, there will be one that sticks out from the rest, and that is the cable that you need to use.

Because of this, you do not have to disassemble the wires and use a tester to identify the one you need.


When you just have one end of a cable wire or a jack and no way to get to the other end, you may need to trace the wire to find out where it goes.

In this instance, you must locate the wire that runs behind the walls of your home and trace it to its terminus to complete the task. In this situation, you will need to apply toner. The whole procedure is as follows:

Connect a tone generating device to the end of the cord that can be reached. This device records the signal from the generator and generates a sound, which aids in the identification of the cable.

Identifying and tracing difficulties

It is possible that the tracing will be difficult. First, you must identify the location of the case, after which you may get the required equipment to trace the cable.

There are a number of different tracing options that you may choose from. Once you have a comprehensive understanding of your situation, you will be able to trace coax cables without wasting much time.

How to Select the Most Appropriate Coaxial Cable Tester/Tracer?

Selecting the Most Appropriate Coaxial Cable Tester/Tracer

If you have a clear understanding of what you’re doing, finding the appropriate instrument shouldn’t be too difficult.

All you have to do is consider the overall length of the cables that you may be evaluating, as well as the kinds of cables that you might be interested in testing. From then, all you have to do is run the instrument through a few simple quality tests.

Cabling Types There are many types of cabling.

As you may be aware, there are a number of different kinds of coax cables available for purchase. Due to the fact that various cables are designed for different kinds of applications.

Some individuals use coax cables to transmit internet video, while others use them to link CCTV networks or radio antennas to their computers. Coax cable comes in a variety of sizes and kinds, the most popular of which are RG59, RG11, and RG6.

What’s the difference between the two?

While the small physical variation in these cables allows for more adaptability to a wider range of installation styles, it also causes them to behave differently when tested or traced using a coaxial cable tester/tracer.

You may wish to look for a cable tester that can handle these basic cable kinds in order to save time.

If you’re searching for one of the more exotic cable kinds, you may find yourself needing to choose a tester that is only compatible with that format.

Electrical Resistance is a term used to describe the resistance of an electrical circuit.

Coaxial cables offer a broad range of impedance values as well, allowing for a variety of applications. Its resistance may usually be found somewhere between 50 and 92 ohms.

You will often discover lower impedance for radio transmitters and greater impedance for high-definition televisions if you are not positive about the lines you are testing. More impedance usually equates to a stronger signal, although the majority of applications nowadays do not surpass 75 ohms in impedance.

If you’re searching for a tool but aren’t sure how much resistance you’ll encounter when testing, you’ll generally want a tester/tracer that can take at least 75 ohms of resistance.

When the tester/tracer does not clearly state what its limit is, it is generally fair to presume that the limit is likewise about 75 ohms since this is sufficient to handle almost all residential applications without causing damage.

Utilization Ease

A good piece of testing equipment should not be too complex. The vast majority of the time, utilizing a coaxial cable tester/tracer should consist of little more than plugging in a cable and pressing a button.

Some instruments, on the other hand, have a more straightforward user interface than others. If you are unsure about your own level of expertise, it may be beneficial to look for an entry-level tester/tracer rather than more expensive equipment.

The length of the cable

There will be distance restrictions for testers in addition to a resistance limit for the cable used for testing. Some of the most powerful tests have the capability of reaching distances of up to 5000′ and beyond.

However, if you don’t really need to test cables that are a mile in length, you’ll wind up saving a lot of money by choosing an instrument that is better suitable for your specific use case.

As a result, if you wish to use the proper equipment for the job, you must first understand the kind of cable you want to examine.
