Can. Just recheck the connection and cables (if the cable is 'injured' anywhere) - replacing it with Astro cable (RG6 cable) highly recommended. In addition, check antenna alignment.

And by the way, is the old antenna equipped with the orange booster box? Defunct boxes can block digital signals...suggest doing away with it altogether (doing a direct connection between the decoder and antenna).

Are you using outdoor UHF antenna? If not sure, can take pic show us.

And try rewire new cable to that antenna using the new RG-6, which is also the same type of cable used for Astro.

Analogue TV broadcasts in both VHF and UHF. Digital is only in UHF.
Make sure the cable connection are connected directly only to your UHF antenna, and not splits into 2 cables to merge with VHF and UHF (if u have VHF antenna). And don't connect to any masthead amplifier (known as booster, typically the small white box that needs to powered on near your TV set).

Yes its an outdoor antenna, no there isn't any booster or sort, however i can't remember if there's a split/merge cabling thing.
Sorry couldn't get a photo or anything as it is in my hometown, and i am doing everything i can to prevent my dad to go up onto the roof. (as he has been suggesting to do so to replace the antenna).

I'm getting him a new TV to replace the CRT + DTV tuner box. But before i do that i need to ensure the antenna works for DVB-T2 tuner else I need to figure out something else.

Seems this set price higher than others, can use wifi to watch Youtube? anyone tried?

RM187 is the retail price for MYTV Advance box.
Watch YouTube? MYTV want you to buy their TV box is only to receive/watch its digital TV channels and its other interactive services, not for other thing else.
No, you can't watch YouTube on that.
Perhaps you can look for Android boxes that comes with DVB-T2 built in tuner at online shopping sites like Lazada and Shopee.

Thanks for your reply, though saw 2 USB port, we can insert the WiFi antenna and watch Youtube like the BoTaTo Decoder.....

How old is the antenna? If many years already just get a new one to replace. Imo no harm but just to make sure you don't need to go get another antenna while in the middle of setting up the new TV.
Regarding the cable, if my old antenna cable is not the screw type, just need to buy the converter right? or rewire is better? Because older TV usually you just insert the cable into the port, no need to screw. I am very sure this is UHF antenna, just the cable not using screw like astro.
Botato decoder got WiFi or Ethernet port? Can watch Youtube and install app also?

You can still find antennas requiring manual termination on sale even today. Those on the market here with ready connectors to accept F plugs you will find are almost always Thai brands.
To carry around just get one of those shorter 5Es lo. Much easier. haha
Can be better - watch the Youtube video I posted above. Make sure the braiding is connected (touching) to the plate, while the core should be insulated from the same.
His old antenna should work just fine. I did part time antenna installation once and aligned dozens of such old antennas with perfect reception and signal strength. Just modify the connection re the braiding.

VHFs in my experience you can use if you're very, very close to the transmitter. Otherwise the performance varies greatly from the UHF.

Hmm, so at least VHF antenna is not totally useless, isn't it? For those that live very close to transmitter can just reuse back the antenna.

I use mine for FM radio.

Use back the big bulky VHF antenna to receive FM radio?  You connect that to your AV system or something?
Why..? Why not use some simple whip antenna or something? Just 1 long stick to get the job done?
Or you do that for the sake of reusing the antenna?

whip antenna is useless in my house. i don't live near the town or radio/tv tower. even phone cellular strength is crappy in my house.
nothing beats outdoor antenna 

Okay... So what FM radio device did you use to connect your VHF antenna? Some audio amps or something?
Can take pic, of the antenna, cable, and the audio amp...
I'm kinda curious though...
Cuz I hardly see, or even never seen those who use TV antenna (VHF) to connect to a FM radio instead of TV. 

Hmm, why manual termination? Cheaper to produce by the manufacturer? ...

Connected to my Denon AVR.
How is connecting outdoor antenna to a FM radio be a weird sight?  In my grandma's house in rural area, even outdoor uhf/vhf antenna is useless. Need to use satellite.

Those "DVBT" USB PC dongles also receive stereo FM radio, so you could use a laptop

Been googling about this with no meaningful result - can you point to where I can pursue this? Very interesting!
