You watch free-to-air Mediacorp shows but do not subscribe to Starhub TV or Singtel Mio programmes. Sooner or later the antenna from your HDB block is not going to give you the free-to-air shows any more. The whole of Singapore is switching to solely digital by end-2017.
Your main TV is connected to Starhub or Singtel, but you have other TVs not connected to Starhub or Singtel. You need one antenna for each TV regardless of whether your TV is the newer Digital TV approved TV or not.
If your TV is not Digital TV ready with built-in tuner, you will ALSO need a DVB-T2 set top box. We sell that here too.

There has been a fair bit of advertisement on this digital thing. What it means to the layman is this:

Starhub TV/Singtel Mio subscribers – do nothing, for those TVs connected to your subscription box. For those TVs not connected to the subscription boxes, you still need to get a DVB-T2 setup box and/or anntena like everyone else.

Everyone else who watches Mediacorp shows:

Existing TV –> get a set-top box + Antenna (can watch and record shows)

Newest Digital TV -> just get Antenna. But you can’t record shows.

We have the DVB-T2 set top box, and the antenna available.

If your TV has either of these stickers, then you just need a digital antenna

Features of this antenna:

It is powerful and lightweight with a 50-mile range. Can be placed on the table or stuck onto a vertical surface.

You can stick it on a window for better reception

Or on a wall

On a flat surface is fine too.

Troubleshooting

“No Signal” message when connected to a set–top box.
Your set-top box may have the Antenna Power ON option set, and it is interfering with the powered amplifier (amplifier is plugged into a power source). In this case, do not power up the amplifier, or turn off the Antenna Power ON setting in your set-top box. If your set-top box can work with a powered amplifier, your reception will be better.

Some free-to-air channels are not showing whilst doing a channel scan.
Try the scan again without the amplifier powered on. The antenna will still work.

Distorted images for selected channels.
The signals are still off-the-air, so if there's stormy weather, certain channels may get distorted. Just shift the antenna around, and try turning on the amplifier on the antenna if it was not powered on before.
