The quality of the parts makes a good impression. About long-term effects such as corrosion, paint adhesion etc. of course I can not say anything yet, but the process shows no weaknesses. Although the instructions are a little on the small side, you can build the antenna with minimal technical skills and technical expertise in almost intuitively and without guidance. The adjustment of the elevation angle is pretty easy thanks to an embossed scale, adjusting the azimuth angle but as with almost all antennas rather tedious. But if you have done it, you can look forward to a signal of sufficient strength and good quality. Only at the level of the signal I had towards the previously installed 60 antenna expected more (1 point deduction)
