Can Kelantan and Terengganu coastal areas receive Vietnam digital terrestrial television signal, despite Vietnam is using DVB-T2 standard?

Vietnam is a socialist republic country in ASEAN, it is also a communist country (but not isolated like North Korea). Regarding its digital terrestrial television switchover, despite China has its DTT standard, known as DTMB, but Vietnam does not follow China to use DTMB standard, instead DVB-T2.


Same with Thailand, Singapore, Malaysia, Indonesia, Brunei and Myanmar, DVB-T2 is Vietnam's digital terrestrial television standard.


In Kelantan and North Terengganu, Malaysia, these region can receive Thailand TV channels, alongside local channels, but as Kelantan and Terengganu are located in east coast of Peninsular Malaysia, so it is interesting whether Vietnam TV channels can be tuned in coastal areas of Kelantan and North Terengganu or not via DVB-T2 UHF signal.


The southwestern Vietnam province An Giang where is far opposite to Kelantan and North Terengganu (divided by South China Sea) has DVB-T2 television services.


In An Giang province, there are two high power FM radio stations (An Giang radio station FM 93.1MHz or Voice of Vietnam VOV-3 FM 102.7MHz) where can be likely tuned in coastal areas of Northeast Kelantan and North Terengganu, regardless tropospheric or normal propagation. As FM and DVB-T2 are on different radio frequency band, but I'm curious if some people who stay in Bachok, Cherang Ruku, Pengkalan Chepa, Tumpat, East Kota Bharu, Kuala Besut and Setiu coastal areas can receive Vietnam digital terrestrial TV channels or not.


Vietnam digital terrestrial TV frequency in An Giang is UHF 490MHz (CH23), transmitted from Núi Cấm. In addition, An Giang has two digital UHF frequencies on UHF 570MHz (CH33) and UHF 578MHz (CH34), but they are standard definition commercial digital terrestrial television.


An Giang DVB-T2 multiplex on UHF 490MHz/CH23 is belonged to Vietnam Television (VTV).

Núi Cấm is also the transmitter site Voice of Vietnam VOV-3/4 FM 102.7MHz and An Giang TV & Radio Broadcasting Company FM 93.1MHz, its site elevation is 705 meters above sea level.

 



Although DVB-T2 and analogue TV are on UHF band, but digital terrestrial television signal propagation is slightly lesser than analogue TV (PAL/SECAM/NTSC). 

 

Generally it is quite impossible to receive Vietnam digital terrestrial television channels from An Giang in coastal areas of Kelantan and North Terengganu, Malaysia as DVB-T2 propagation does not overspill much signal as analogue TV and FM radio, unless there is tropospheric propagation and TV viewers install another outdoor antenna to beam to east direction to receive Vietnam TV channels from Nui Cam, An Giang Province.
