Already nice and high, but that is not a high gain antenna

This one is better
https://www.lelong.com.my/upgrade-phison-hi...7-01-Sale-I.htm Actually a 12 element It would give about 2dB more gain if it did not cover all the way up to 860MHz |

There are bypass relays at UHF, but they are expensive

This is a better example, decent gain and deliberately limited bandwidth to reduce LTE interference

QUOTE(joshhd @ Dec 16 2019, 09:52 PM) I'm like never see this tri-boom type of antenna before in around Malaysia... Because it's not commonly used? Or this tri-boom type is expensive to buy? Tri-booms work. A single boom of similar gain would be about 1.5m long.Is it really proven that this tri-boom type really improve reception a lot, compared to non tri-boom types like what we usually see in Lazada and Shopee? And the reflector looks so damn big wehh.. Useful for aiming very far away transmitter?  |

QUOTE(joshhd @ Dec 17 2019, 10:02 AM) I know it works... But why is it rarely used though? Just down to what is available from the local importers.Most of the time I see is one single boom ones, if it's a lot of elements. They like us to waste money on tiny antennas with a booster. The booster does nothing useful if the cable is short |

QUOTE(trickyhunter @ Dec 19 2019, 11:47 AM) Wrong That is a clash with the so called 700 MHz LTE band being 698 MHz to 806 MHz Bukit Larut is use 665 for media prima 697 for RTM  |

Not many places 11km from Menara KL actually have line of sight, too many tall buildings have gone up. The Bkt Sg Besi transmitter is at about the same height, but much clearer surroundings

Googleearth and Garmin Basecamp are good on PCs for finding best aiming direction

Broadcasting in rural areas of Malaysia is a very expensive project, so don't expect to match Singapore bit rates.

Because Malaysian property is built with rebar concrete and use metal window grilles, outdoor aerials are usually a good idea, even a five element at roof height is much better than any indoor plus booster

QUOTE(yongtjunkit @ Dec 26 2019, 07:47 AM) The cable splitting happens outdoor, does this means that there’s no in line amplifier, looks like hobby grade splicing to me and it’s covered with tape by the landlord Crude splicing gives much more loss than a proper splitter (which can be only 3dB loss)Most of the time only 1 TV would be used at a time The unused section still wastes signal even when the TV is off or disconnected |

The antenna is a dual band design. The VHF III part is now obsolete after analog switch off. It is possible that the trailing cable is connected to the VHF section

But remember that the RM90 DVD player that you bought in the supermarket only lasted one year

4G or 5G makes no difference to the potential interference that this will cause to DVBT2. I notice that there will only be one 700 MHz infrastructure licence, to be shared by the usual suspects. 30+30Mhz pretty much uses up all of the 700 MHz

Langkawi has the geography that suits 700 MHz 5G, so likely to be the test network. Restacking TV makes the trial possible

A lot depends on what happens to TV Channels - especially will Media Prima survive the next few years in competition with streaming?

Given the multiplex rental costs, it is an expensive marketing method for frying pans

You cannot see the pixels on a 60" 4K TV, so UHD is rather pointless in most peoples houses.
HDR done properly is more interesting, but does require a much higher bitrate than any Malaysian broadcaster use |
