Good antenna for little money.

With radio you have to watch. The many opinions that the antenna has no good at 99.9% nothing to do with the antenna.
I have relatively poor radio conditions (Fritz box upstairs and the ground floor will have reception and DG). Without the antenna with the Fritz box with no chance.

I have attached two of these antennas to the Fritzbos and in an installation shaft down and oriented upwards.
Since then I have anywhere in the house from the basement to DG reception. Before not even anywhere in the EC.
Average he rose to 5- 10 db. The fact that I was able to experiment on the orientation aside by the antennas (compared to the built-in the Fritz box), even 20dB gain were partially drinn (Fritzbox the laptop less than -80dB and reception with this antenna and appropriate placement went to the reception to -60dB high.
One must not expect too much, the receiver is now time depending on the environment.
I hoped something that in 5GHZ enter similar improvements, since the frequency is pretty much twice yes, but was not.
