QUOTE(joshhd @ Nov 6 2019, 12:59 PM) If you ask this to MYTV, their answers would be like: "Oh, we invested millions to billions to build the DTT infrastructure in Malaysia, and provide Malaysians digital TV broadcasts for free, and viewers just have to use a DVB-T2 box and UHF antenna to receive it. It's not for free, RTM and Media Prima etc have to pay a (large) monthly rental to be transmitted. The question is whether MyTV have actually met the contract requirements to be paid. Their coverage looks very below target to me. |

QUOTE(joshhd @ Nov 11 2019, 07:44 PM) Hmm, why manual termination? Cheaper to produce by the manufacturer? ... It does save money, but also reduces losses. It also saves you having to put a matching plug on that end of the downlead and making an outdoor connection waterproof is not easy. |

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

These SDRs are easiest to use on Linux, but there is a Windows program to use them https://cubicsdr.com/ |

You can find these dongles on sites like Lazada for about RM30 each, search for "sdr"
They come with a spike antenna, a remote control and a mini cd of TV display software

The wiring from the coax connector to the element looks very corroded

QUOTE(joshhd @ Nov 25 2019, 11:57 PM)  "DTH transmitters"?? Err... hmm...  Look closely at the narrow section at the tower top and you can see standard flat panel UHF transmitter antennas Ignore the PDRM? antennas at lower levels This post has been edited by dayojah: Nov 26 2019, 11:35 PM |

Most high power UHF transmitter panel antennas are like these: http://www.elti.com/p/9/9/uhf-four-field-antenna-panels.html |

QUOTE(Nervous Levin @ Dec 2 2019, 03:20 PM) where can i get the list of "exact coordinate" for the transmission towers? i want to install outdoor antenna myself, but want to make sure it's pointed to tower from the right side of the house. Cento Digital TV Antenna Outdoor-Indoor CT-HDOF3 This map seems accurate https://www.mytvbroadcasting.my/liputan_siaran/ |

QUOTE(AV_2018 @ Dec 4 2019, 11:19 AM) Could it be signal too strong and overload the tuner or caused clipping? Possible, but unlikely with MyTV, except in some of the condos near Menara KL |

QUOTE(chuppachop @ Dec 3 2019, 06:38 PM) Thanks AV 2018 & Shaun, I read Hong Kong TVB transmit at around 14 Mbps .... but that was quite some time ago .... not sure if they have lowered the bitrate .... interesting how Hong Kong can go so high, haha. The same reason Singapore can - tiny coverage area, so no need for dozens of transmitters and the very expensive satellite links feeding the transmitters. For comparison the UK uses about 6 Mbps for a HD channel |

QUOTE(joshhd @ Dec 6 2019, 06:12 PM) Didn't expect that frequency retune exercise would carried out that soon.  Looks that they want to start testing or using 700MHz from Jan 2020 onwards in and nearby Klang Valley areas, and of course none other than Langkawi, the best place to do 5G testing and many other reasons.  Langkawi will be pressure from Thailand to get off 700 MHz. A pity that KL MUX1 is still to be on 666 MHz, filtering off 700 MHz 5G is not practical so close in frequency |

The individual panels are wideband, but the panel vertical spacing may need adjustment for lower frequencies.
Genting is considered a border transmitter as it easily reaches the coast of Sumatra, due to the extreme height

Singapore will have to give up or share some of the ch26-38 in exchange for being able to use ch50+ for 5G, only fair

QUOTE(joshhd @ Dec 10 2019, 10:16 PM) Cuz MYTV gonna use up to 3 muxes for now. Now even with 2 mux still got some remaining unutilised bandwidth. It's unlikely to see existing or new broadcasters/content providers would offer new, and TV channels onto their platform that are able to sustain for long... That's my forecast la... Cuz not many Malaysians today are watching TV on regular basis anymore, unlike 10+ years ago... All online dy.. Astro is vulnerable to satellite failure and Netflix etc depend on the international cable actually working. Both depend on foreign governments to function. Terrestrial TV is actually a reliable fallback |

QUOTE(shaun_kok @ Dec 11 2019, 11:22 PM) Agree with that. Satellite TV (C-Band) is extremely reliable, with 99.995% uptime, after considering sun outages that will happen twice a year. Ku-Band is not reliable whe compared to terrestrial TV/C Band due to weather issues. Sun outages is different in each area so if one area is affected, it will typically not affect other. Only very selective users, like the military, require more than 1 satellite as they require 100% uptime. DTT is very realiable too, but however it is subject to transmitter outages. But since no one want to have 2-3 meter satellite on their house due to legal issues/looks ugly in some situations, DTT remains the best system. Satellites are potentially vulnerable to an accident or attack in the geosynchronous orbit filling the orbit with shrapnel as in "Gravity" C band is under threat from the US, who want to use the band for 5G |

QUOTE(nightzstar @ Dec 13 2019, 12:52 PM) Sorry is 38km as per Google maps. Lol 38km is not far for a main transmitter. More importantly, do you have line of sight to it? Tall buildings and hills block the signal |

An unpowered booster would reduce, but not completely block the signal compared to not having a booster at all
