This antenna I ordered after reading some customer reviews here on Amazon and it was delivered very quickly. My landlord does not allow bowls on the facade and so I needed something that I could place outside on the windowsill. When installtion but then turned out, the space on the inside to be completely adequate. Have in cloudy and rainy good reception and can also look HD channels. In heavy rain I can not test - is possibly replenished as reporting. :) Now I am building for my window sill only a small boards with an appropriate angle so that the antenna can be easily pushed against it and so at the correct angle (azimuth) is - so I can quickly put away even then. The tendency fits after screwing the bewegl. Parts and readjust low - so I did not need any special fixtures.
