[QUOTE="John, post: 993556, member: 175005"] Thanks [USER=233155]@pride21[/USER] , i can see that it is the reflections off the foil ? on the side steps that give a false impression of their actual size etc. Tuning these modifications to obtain maximum can be a bit of a task .... iv'e just tried yesterday for many hours, tuning a cone scalar on my homebrew polariser for Extended Cband and failed. The Titanium stepped scalar turned out to be the better match for this particular barrel with just over 1dB better performance. Your measurements seem to check out, it might just be a matter of a bit of fine tuning on the steps thickness measurements and careful scalar to barrel throat positioning as i have found this to be pretty critical to get maximum performance. Are your top and bottom step arrangements running true to each other etc ?.
