I placed it indoors about 2 meters above the ground in the Neos Kosmos area on a hill, it barely works at all

Unfortunately, it did not work for me. Despite the fact that I am on the ground floor, the result is zero. Wasted money. I will now get one with an amplifier

The antenna is not bad. It's just that the location where we found signal did not suit us, so we did not use it. We preferred to run a cable from the main antenna.

For indoor use in Kallithea, 1st floor, surrounded by apartment buildings, signal strength is zero everywhere except on the balcony, in a specific spot where it operates with 100% signal quality and intensity ranging from 55% to 80% depending on the frequency, thus providing a correct image. Look for a spot based on quality and less on intensity, considering that televisions have AGC.

I really saved myself from cables and antennas on the rooftop. I placed the TV in a spot where the house's antenna cable couldn't reach, so by buying this, I didn't have to do anything else besides connecting it to the TV and sticking it with a sticker that it comes with right behind the TV. It doesn't even seem like it's there, it works perfectly and it's very lightweight. It's worth trying it for its price.
