Quad Ridged Horn Antenna Feeding - HFSS

Hi, I have designed a quad- ridged horn antenna. Before connecting SMA Connector to my antenna, I would like to test it without SMA. Therefore, I need to feed my antenna with waveport. My question is "how should I oriente my waveport to test my antenna without SMA connection. How should waveport line be positioned?" Could you draw it in paint and paste it here?
