The antenna has not convinced me. I bought the antenna after I read so many positive reviews. After unpacking I've found that has a power supply included. Power consumption is given as 2 watts, which is not too bad, but unfortunately these are not information in the description. Processing is not the upper class. From the pictures the impression that there is antenna made of plastic is produced, but it is not so. The antenna is made of plastic, from which the water wings or inflatable air mattresses are made. To receive I can only say, with passive antenna I get better results. Pricewise there nothing to complain about, but all together, not convincing.
