Can consider making a simple
DIY fractal antenna that works really well in my own experience. Just 10 mins or less, most materials already have around the house: A4 paper, clear plastic sheet (I recycled from front cover of old report with binding), kitchen aluminium foil, glue stick, 2 small screws like those used in PC DIY.
The 75-300 ohm balun transformer is the only item that may not possibly be readily available: can get one for $5 from 2nd floor audio/mic shop at Sim Lim Tower (maybe even cheaper from other shops). You can Google the image to show the shop owners. I also saw a cheap $3.20 dipole antenna at Sheng Siong (maybe even cheaper at neighbourhood stores) that you can dismantle to use the balun transformer. Better if still got old antenna lying around to be salvaged without spending a cent!
I was very skeptical that such a simple non-powered antenna, that costs zero to a few dollars to make, can have decent performance. But wow, it picked up all the local DVB-T2 and DVB-T channels with signal intensity 80+ to 99% and signal quality about 98%; video & audio both very smooth (as good or better than from Starhub cable point) even for HD channels like HD5 & HD8. Only thing is I have to place mine right next to window (I think my area not indoor reception-ready yet). If antenna cable not long enough, can join up shorter cables using adapters ($2-3 at hardware stores) without having to buy a new long cable.
No harm trying this super cheap yet good method. I also tried another DIY method using CD case and binder clips, it could receive signals but choppy video for HD channels. Have fun!
