I think it has got to do with location problem. Personally I also cannot get good signal with antenna indoor.

bro, you need a powered antenna with built in amplifier. mine is 20dbi usb powered, which amplifies 10 times the signal received.

You could go mustafa, ntuc, hardware store find those powered type with high amplifier gain e.g 100dbi = 100 000 times the signal receive though also amplify the noise. If you like to try out my antenna on my thread kindly msg me. if no work then you can return and i refund back is all right troublesome though.

A tip for those DIY dipole antenna, there is a mistake, recommend
to tune to 522MHz. See sites on the internet the half wave length should be 147/522Mhz = 28cm

...

I will try to look for some cables and maybe DIY with the connector head. May i check if those electrical wire will work? Like those black/red insulation cables (inside is probably also strains of copper wires)
If you have spare electrical cable, no harm trying. Untwist about 12 cm of the cable to form the "T". No need to strip the insulation. Right now I don't have a male IEC plug for the tv connection to test out. Will try to improvise one when I am in the mood.

There is no mistake. 522MHz is the centre frequency of chan 27. Ignoring reception for chan 38, the antenna made for Singapore should cater for the reception of chans 27, 29, 31 and 33. The centre frequency for these four channels is 546Mhz. Half wave length minus about 5% = 150/546 x 0.95 = 26 cm.

Note: the 5% reduction is only a guide. Actual deduction depends on a lot of factors - for academic interests only.

If one wishes to cater for chan 38, then the dipole has to be shorten.

In any case, the exact length is not critical. My prototype eventually had a dipole length of 16 cm only. And it works

One advantage of buying approved set top box from local trader/supplier, compared to buying from overseas, is that even if no warranty is expressly given, the buyer is still covered by Lemon Law.

I have used V antenna for about 2~3 month already to receive HD channel. So far it is OK. It there any different for quality of images as sometime I checked the signal quality is 50~60%. But images is still steady and clear.

sounds like a location problem.

I suggest you hook this type or equivalent catv amplifier to the matv point, available at hardware stores, sim lim tower, a bit costly though

from this thread, i have seen ppl received strong signal with the antenna indoor
can anybody recommend me antenna that i can use indoor ?
as it is quite impossible for me to wire my antenna outside
Just to repeat for those new to this thread, there r indoor n outdoor coverage for dvb t2. Just wait for ur area to have indoor coverage ready n u will be able to recv dvbt2 easily anywhere in ur house.

today i tested the DD/DD+ surround for 5HD on my 5.1 Home Theatre System (HTS).
i watched the 5hd afternoon movie "dirty dancing" on my starhub ch155 and confirmed it is broadcasted in surround 5.1 (the conversation comes from my HTS center speaker, all 5 speakers got diff sound.)
then i used my draco dvb-t2 stb to record the same movie in TS format and plugged it into the same HTS. confirmed that DD+ (sound 3) audio can work on my HTS (i think it's due to DD backward compatibility). dolby logo is displayed on HTS, and conversation comes from my HTS center speaker, all 5 speakers got diff sound.

as for AAC5.1 (eng) audio track, only front L/R speakers got sound, sound is good just without surround (maybe due to HTS cannot support 6-channels AAC).
for AAC (sound 2) audio track, normal stereo is heard. the sound is louder and feels like it's downmixed sound.
also played my 8HD recordings through the HTS. AAC5.1 and AAC same behaviour as 5HD.

That's the beauty of dvb-t and t2 technology. You will always see perfect picture even when the signal is less than perfect. If the signal drops below the threshold, the picture just freezes. There may be occasional pixelation just before picture freezes. I supposed you have not come across such situation yet.
