Choosing the correct cable to connect DVB-T2 television to aerial wall socket

Since August 2019, Malaysia free over-the-air television broadcasting has been switched from analogue to digital.

The good news is, nowadays most newer model of television has built-in DVB-T2 decoder to receive digital over-the-air TV channels.

If your house/condominium/apartment has an aerial wall socket that connects to the external aerial antenna of the building that looks like the one below, you can use a TV cable with male-to-female connectors to connect your TV with DVB-T2 decoder to the TV wall socket and receive the broadcasted digital TV channels.

If your TV is facing problem of missing channels, pixelated screen, snowy screen due to weak signal strength and/or weak signal quality, it can probably be caused by the type of cable used.

Referring to the table below, if you are staying in a highrise building, the cable buried inside the call connecting the wall socket to the external antenna should be coaxial cable of type RG11/U.

If you are staying in landed property which the distance between the external antenna and the wall socket is below 225 meters, then maybe RG6/U cable still be used without much problem.

For the portion of cable connecting your TV to the wall socket, RG6/U cable is recommended. Using RG11/U cable is even better, but its cost will be higher too.

If you are using RG59/U cable but don't face any problem with your TV, then you can continue using it, otherwise, consider upgrade the cable to RG6/U.

In the photo below, the black cable is type RG59/U and the white cable is type RG6/U. You can easily notice that the RG6/U has a much thicker diameter than RG59/U.

If your TV problem persists despite using RG6/U cable, you might probably need to resort to other solution, such as adding a signal booster, using digital TV decoder box, or receiving the TV signal using an internal antenna.
