Some time ago I designed 21cm interdigital filter usin VK3UM app.
wa4dsy program also gave very similar out (for 0.1dB ripple).
However, when I build it, the best adjustment I could do is as per attached image.

I tried to understand which parameters should be manipulated to obtain the same result, so I tried RFSim99 simulation as below

Could someone tell me if this equivalent schematic is adequate?
