Yes. Contact your building management, ask if whether the MATV (Master Antenna) system supports digital TV or not.

If not, and your building management refuse to upgrade the system, then your last option would be using your own TV antenna.

What is your apartment/condo name? Which city and state?

Centralised antenna system (MATV) must be upgraded to support/receive digital TV signals due to technical reasons. Otherwise you won't receive any signal at all.
Malaysia's analogue TV broadcasts has been switched off end of last year, so it's no more already.

Or else, you'll have to use your own UHF antenna.

You can consider get antenna models like this, which is known to be pretty good:

Since the antenna is small in size, basically you can just place it anywhere near the TV as long you get a good reception, so not necessary must put outside of your house or something (depends on location too).

Or, you want to buy an outdoor one also ok:

As for the cable, please use RG-6 cable instead of 3C-2V or 5C-2V cable, for a better overall cable performance = better signal reception.
RG-6 coaxial cable is the same cable type used in satellite TV, such as Astro.
