Subject: | [Towertalk] "Real" Height of antennas on Buildings |

Is there any reliable way to tell what the "real" height of a yagi is that's on top of a building? In other words, electrically how high the antenna thinks it is. Is there a formula to calculate this if one knows all of the critical information (dimensions of the building, antenna height above building, etc.) and assuming that the building is a 3D square or rectangle? Are there any rules of thumb for this or is modeling the only way? 73, Nat, WZ3AR <nat@ajheatwole.com> |
