It was installed without difficulties and searches, and the result was a clear and uninterrupted signal and image. Notably, the power cable ends in a USB-A male type plug (with power requirements below 1W), and a USB-A female to socket adapter is included. Note that it is used in Eastern Attica. For areas with a lack of transmitters (mountain tops, etc.), further investigation may be needed. EDIT: I was satisfied enough to purchase 2 more pieces for the family. Highly recommended.

It was installed 4 months ago on the edge of the window sill, in a room on the 3rd floor of an apartment building with other apartment buildings nearby in close proximity. It is worth noting that the window overlooks an opening with a mountain across, so this probably helps a lot because the signal is excellent, without any interruptions and for all channels. It is highly recommended for such use!

Very good, just there are moments when it completely loses signal and you have to do acrobatics to get it back!!!! Otherwise, it's fine!!!!

Connected to a modern technology HD television (DVB-T2) in the Athens - Center area (4th floor) in a room with no obstacles. Me and for 3 years everything works perfectly like the first day.

I placed it in an area of Athens and it has perfect signal without needing to shake it every time you change channels. Otherwise, easy installation and discreet size!

Only with the power supply boost, you have a chance to see an image (so it needs a power outlet), and this only in an area/position with relatively good signal. Compared to the makeshift antenna (a simple TV cable, with 30 cm stripped at the end), it has worse reception with the power supply from the TV and slightly better with the power supply. On the positive side, it is very small and discreet.

Very good signal, I can catch as many channels as I used to catch with the conventional antenna of the apartment building.
It has a very small size, a very long cable, it has a magnet on its base, and a power supply for its amplifier is also included in the package.
