How Do I Test My Coax Cable Signal?

Learn > Coax Cable Tester > How Do I Test My Coax Cable Signal?

Coaxial cables are very common in many apartment buildings, homes and offices, using them to obtain a fast and reliable internet connection. However, ensuring that connectivity can be a process in older buildings that have had many previous tenants or have undergone renovations. When you need to accurately verify if there is a valid signal being received by your coax wiring, testing your coax cable wiring or coax outlet for a signal is a relatively simple process and can help solve various connectivity questions like the above, as well as:

  • Discovering which coax cable connection is a ‘live’ connection receiving signals from your cable Internet service provider.
  • Testing which coax outlets are live and receiving valid signals.
    • Note: over time, coax cables can be moved or removed, losing their original signal. Testing your cables is crucial to verifying the connectivity of your internet without incurring the cost of a technician’s visit.)
  • Testing endpoint coax wall outlets to find if a signal is still being transmitted to them.

There are two main ways to test your coax cable connection and coax outlets for a valid RF signal. The more labor and time-intensive way is taking your internet modem from cable outlet to cable outlet, individually checking each outlet. If it connects and locks on like normal, the connection is receiving an RF signal. If it doesn’t automatically connect it isn’t. This route tends to be more cumbersome and takes longer, but it produces the desired results.

Enter: the pocket-sized DSS-01 Coax Cable Tester.

The DSS-01 Coax Cable Tester has a unique, compact design, fits into tight, hard-to-reach areas, and is easy to use. This low-cost tool is a simple solution when it comes to testing your coax cable connection or coax cable outlet. The DSS-01 uniquely identifies specific ranges of Radio Frequency (RF) signals that your Cable Internet service provider uses.

Simply plug the DSS-01 Coax Cable Tester into a coaxial outlet and press the button. You will start receiving results instantly (in less than 10 seconds),  the LED-light indicator letting you know whether or not you are receiving a valid RF signal (blinking green or red, respectively). Because the Coax Cable Tester only detects RF signals within a specific range, you won’t receive false-positive readings, unlike many other solutions that detect voltage. Additionally, other products may require two people to test effectively, but not the DSS-01Coax Cable Tester.

The DSS-01 Coax Cable Tester is an ideal tool for anyone who needs to test a coax outlet or coax cabling to ensure a valid signal is present.  Perfect for renters, home owners, home builders and technicians alike.
