As it turned out, this is an ordinary getinax (who else calls textolite), on which the same Board is etched as a vibrator, and as a reflector and the back cover - a stainless plate. Getinax thickness is 1 mm, the distance between the vibrator and the reflector is 10 mm. Dimensions are attached (sorry for the quality, quickly made in paint-e). Very easy to repeat, anti-crisis solution . The gain factor was compared with the same 17dBi grid, which was slightly lower than the stated value . Most likely, they are made in Ukraine, although Poland is listed as the manufacturer. If anyone has heard anything about their production , we will share our knowledge .
