  Amazing product. Since my neighbor installed an outdoor WiFi antenna in front of our antenna (Frequency Band Range: 0.698 - 5.000GHz on 5G), while the signal strength remained stable and our amplifier had no issues, the BER errors increased, meaning the signal quality was affected and it would drop significantly, resulting in signal interruptions. I am attaching a photo of the WiFi antenna.

  Attention. On the packaging, it states the two connections with or without an amplifier. The amplifier is represented by the black triangle, so the filter should be installed before the amplifier, before amplifying the 4G or 5G interference signal. Of course, the 5G filter also cuts off the 4G signal. I experimented by trying it after the main amplifier, but I didn't even get mediocre results. However, with the correct connection, the Egnatia channel, although its power dropped slightly from 46% to 38% (the 1dB attenuation mentioned by the filter), the signal quality reached 100%, while before it ranged from 0 to 20%. Needless to say, the HD channels also reached 100% signal quality, while they used to have interruptions. In some channels, the signal quality reached 100% without the power dropping, in fact. I am also attaching a photo for the skeptics. If I had only installed a second amplifier with a 5G filter on the first floor, I wouldn't have achieved such a good cleaning because the interference signal would have already been amplified in the main amplifier. That's why LTE antennas with integrated 5G filters exist, after all.
