Mounting design for B5 link

I am trying to figure out the height to mount a B5 unit to clear the edge of a roof top that is 60 feet away. The other B5 unit is 2.75km away. I’m trying to find an outline calculator but have had no success. Can anyone point me in the right direction. I am new to this type of installation.

Have you ever seen radio mobile (software)?

I can run the path for you if you give me the co-ordinates and heights. I can then tell you the clearance close in.

With that short of a path I don’t suspect you’d more than a foot or two at 60’. Of course it also depends if you are shooting up or down to the far radio. Its simple, hosted, flexible. It’s been a great tool for ptp links and ptmp coverages.
