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.
