I actually was skeptical before buying. It stood at a new 48 inch televisions, so far I have a DVB-T antenna on the balcony had good experiences. Now all cried, you need a new antenna for this device so that you can receive HD On the roof of our apartment building 10 we got a new SAT Anlge few years ago, I then connected the TV there, a disaster, just a WDR-station I was in HD. Then came the Selfsat H30D1, my friend came with a SAT-Finder and in half an hour, the antenna was installed, I do not believe it until now, because what I receive at stations, for me this small antenna is a technical marvel. Very positively, the packaging, arrangement of parts and fit all parts in the assembly. In short, the hammer itself. I'll still try the antenna between our flowers a little to disguise eg with a printed film, have been tentatively a plastic bag pulled over the antenna, it had no effect on the reception quality. So, I think, so that says it all
