Well, this little antenna is a beast. We installed it on a small balcony in the city center surrounded by apartment buildings with no openings, providing signal to two televisions and it picks up everything perfectly. And the HD channels, of course, and the radio stations. In terms of size, it takes up minimal space, it is very convenient and easy to install. You need to buy one plug, although more or less everyone has some spare at home. And its price is truly unbeatable. So far, there have been no complaints about its construction. And it's nice to look at since the big antennas are ugly and functional.

Excellent signal, although the build quality is very simple, don't expect anything crazy. It is very easy to install and requires a coaxial cable with an F connector (screw-on) from where the antenna starts in the square plastic box and terminates at the other end with a simple male coaxial antenna plug. I didn't see any distortion in the image even in the rain. It works like a charm!
Only time will tell its durability against oxidation, etc.
For now, 5/5 even though for its value, around €10, it is very okay.
