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

Yes. Effective for my outdoor antenna.

If connect this amplifier to the antenna, and if you don't connect the USB to a powered USB port, the reception/signal strength reading will become 0%?
Or it will be the same reading as before connecting amplifier?

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

Hmm I see...
Thanks for the info..

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

Are you suggesting me to change antenna or just get booster? I plan to get idtv

Hmm, that TV antenna design looks uncommon.
Any idea how's the reception like? Compared to the usual 5 elements antenna for example? Same only?
What's the speciality of this kind of antenna design?

Hmmm... Try readjust your antenna and monitor signal readings first. Like rotate left and right, and then ask someone to monitor signal strength reading.
Or else, relocate that antenna to somewhere else around your house, but almost as high as that is fine. Maybe there's some obstacles or hill are along the signal path....

Or else, consider either a booster or buy an UHF antenna that has more "elements" (the metal rods) for better reception.

Using either IDTV or DVB-T2 digital TV box doesn't matter.

Thks for your suggestions. Will try to relocate the antenna and see how

This one is better

Actually a 12 element
It would give about 2dB more gain if it did not cover all the way up to 860MHz

0% as if there's an internal relay

Hmm.... It won't just passthrough without power?

it won't.

There are bypass relays at UHF, but they are expensive

Your antenna is is low gain since has 1 director element I think.

Get longer one and see the result. If still not good, then add booster. At 38km, I think no need booster.

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

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?

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?

Yeah yeah... CJ Wow Shop is not going anywhere soon.
Don't expect them to air much more nice TV programmes on Media Prima channels.
