If a PTP670 ODU will be installed on roof of a building with 30m high with the antenna pole of 3m on the roof of the building. When carrying out the Link Planner simulation, should we input the 3m or 33m height in the Link Planner as antenna height ? According to the linkplanner user guide, the antenna height refers to height above ground level. Does it mean the terrain ground or the roof ground ?
You need to add up the building + mast for the antenna height for your link.
