DVB TV Tuner Thread II [consolidated]

The Hauppauge Tuner comes with DVB-T Antenna right, is it good enough?

Not to worry about the antenna. All signals, including analogue tv, "digital" tv, satellite tv, 2.5G, 3G, etc, passing through the air are in analogue, modulated in different ways. The received signals, after passing through the tuner, are then by ADC conversion for further processing (see typical pic below for illustration)

The only difference in the antenna design is to cater for different frequency spectrums.

Can someone with working dvb-c tuner card please check how many channels are being carried on 370MHz, besides the Ch 5(HD)? Thanks.

Seems to have a Asiannet Movies channel, HBO HD channel, and HBO Hits HD channel. All encrypted.

Appreciate your quick reply. Thanks once again.

DVB-t and DVB-t2 share the same antenna, but antenna for analog tv has different considerations.

One of the main problem for analog tv is the ghost image, and it needs a much better antenna to reduce the problem, therefore the antenna is much bigger due to the need for high directivity.

One of the main problem for analog tv is the ghost image, and it needs a much better antenna to reduce the problem, therefore the antenna is much bigger due to the need for high directivity.

My "analogue" rabbit ear telescopic antenna works perfectly, hidden inside the TV console, to receive "digital tv" signal when the elements are shortened to minimum to form a half wave dipole. Similarly, a simple folded dipole of about the same dimension sold locally since decades ago to receive Batam and Malaysian analogue tv, also works perfectly for digital tv signal. Some even managed to pull in weak digital signal from Malaysia

More directional antennae, such as Yagi, were also made long before the advent of digital tv, to overcome the problem of multipath reflections and pull in weak signal in fringe areas. The common denominator in the design of these antennae is the wavelength. For maximum efficiency, the dimensions of the antenna elements is tied to the wavelength of the frequency spectrum.

The terrestrial digital tv standards, such as T1 and T2, has been produced to take care of some issues in analogue tv transmission and reception. The end result is so good that the signal (including that for transmission) required is very much reduced compared to that of analogue tv. Furthermore, multipath and other interferences encountered in reception are also effectively eliminated by digital techniques.

Because of these measures, antennae made for digital tv reception can compromise their physical dimensions even though the signal received is not of optimum strength based on wavelength consideration. In any case, digital tv antennae based on Yagi, such as Funke YagiNX, are being sold. As it's product brochure says: "...put the performance of larger antennas in a small package..."

This new version of Astrometa stick works to receive local DVB-T2 broadcast. Using it with Libreelec which has the driver for it.

Is there such a thing as a dvb-t2 tuner stick that I can power via USB and connect to a Minix U100 android box?

Yes there is, but u must be able to load the drivers in the android box though.

I think if u just want to receive DVB-T2 on the TV, then just go for a DVB-T2 box and not buy the USB one.

USB one is more for PCs and laptops.

Hey I did succeed but probably only for 5 minutes maximum

I have issues with the signal and antenna in my room .
I must keep holding my hand up high to get any signal at all. Not a very comfortable experience I must say.


Used this as the driver

And this as the software

you need an active antenna such as funke dsc550

Actually I was using this. Does the Funke DSC550 really make a difference?

you did plug in the usb header right?

anyway, reception is best near windows, the further inside your house, the less chance for a good reception

Eh my android box doesn't have enough usb slot to plug on the usb header

So I plugged it into one of those aukey multiple usb charger things to provide the additional power source

That's true cause as you can see in the photo the part I am putting the antenna is opposite from the monitor and the android box with the TV tuner

Behind the camera is the window.

This is the signal with the active antenna plugged in and the antenna dragged across the room to be hung on the window

Kind of a tripping hazard actually

something wrong with your antenna.

normally the signal from an active antenna should be 100%, even when you are not able to see pictures on tv.

if the signal quality is more than 50%, you will get good picture.

it seems like you had not power up the antenna.

Either that or the antenna needs to be directly plugged into the minix U100 box instead of the aukey pa-t15 adapter I have

Anyone using DVBviewer on Mygica T230? Which version is stable? And are you able to tune if Tuner Type set to cable?

Using DVBViewerPro 6.1.7.1 (latest liao) on Mygica T230.

The DVB-T2 channel range for Singapore start from 538 to 570 (if you want, you can start scanning from 400 to 800. Had tried, no additional 'hidden' channels). The transponder list, I just use DVB-T Europe. Some of the other countries have 1/2 step tuning also.
