Have this antenna bought for Easy Box 904 non LTE as the internal antennas are a bit too weak. This requires that you make a hole in the Gehäise and adapter kaugen these are then simply plugged on the board. I have this connected to the 5 Ghz channel and now the reception of W-land is much much better than before. Can I recommend everyone and always remember Longer is not always better! :) The higher the frequency the smaller the antenna.
