I need help in horn antenna

Hello,
I'm doing a project about "quad ridged horn antenna for UWB apps".
I build an antenna according to some article but I don't sure that i did the coaxial probes right.
The probe have to pass through one ridge and then to connect to the oppsoite ridge.
I'm asking for somebody to check my coaxial probes and tell me if they alright.
