I use the antenna here on a garage roof (west of NRW) on a sidewalk stand plate. The construction and assembly of the LNB is simply stable holders and obviously high quality material. At the back of the antenna is mounted with two brackets and wing nuts on the mast. Thus adjusting the antenna followed by tightening the screws succeed properly without the alignment adjusted again. The also applies to the setting of the azimuth. I operate my satellite system with the 78 cm-Fuba Bowl, the Premium Inverto Twin LNB and 120-DB cable. With these components, I can still almost 50 m cable installed a signal strength of approximately 58% and a signal quality of more than 80% on the receiver Technisat S2. So you need not have a separate amplifier for these cable length. Even with heavy rain and thunderstorms the reception was so far without any interference. From me a strong buy recommendation!
