I have a question about a USB receiver for DVB-T TV signals. This is a USB device that you can attach to your computer, and you may receive some stations.
I have 3 questions about:
1. You should not be too far from a DVB-T transmitter station, is itself about 22 km from the nearest station (20 KW transmission power), is this too far for a good reception?
2. On some sites I read that such devices only allow 1,2,3 and regional broadcasters to receive, and I also read somewhere that other commercial channels you can receive, what is true?
3. Makes it very much difference in these products if I have a very expensive or take a cheap?
I am a layman in this area, so thank you so much already!
