How to extend wifi 200ft? Engenius NH500

[TrenZelor on PC]

I purchased the Engenius NH500, only one unit though. How do I set it up. Esecially I'm trying to share the internet from the church to a parsonage across the street. What other units do I need, if any? What way do I need to set it up as? An access point, bridge, ect..
Thanks!
