MLinkPlanner can calculate the height of main and diversity antennas using the clearance criteria described in the Recommendation ITU-R P.530.
To calculate minimum antenna height, click the icon next to the desired antenna. In the window that opens, specify the optimization parameters.
You can change the following parameters:
- Climate - Temperate climate or Tropical climate;
- Type of obstruction - obstruction is extended along a portion of the path or single isolated path obstruction
- Calculation Criteria - Standard or Less conservative criteria. Less conservative criteria may be necessary for frequencies less than about 2 GHz in order to avoid unacceptably large antenna heights.
- Standard k-factor - is the median value of the k-factor (equivalent earth radius factor) for standard atmosphere. Can be modified by the designer.
- Extreme k-factor - it is the lowest expected (minimum) value of the k-factor, computed from ITU-R Rec. P.530-17, as a function of path length. Can be modified by the designer.
- Part of Fresnel Radius - it is part of the First Fresnel ellipsoid is required to be free of any obstruction for the appropriate value of the k-factor. Is automatically determined depending on the Type of Climate, Type of the Obstruction and Criteria from above, but can be modified by the designer
Once the required preferences are selected, click Calculate antenna height and the minimum antenna height will appear on the right. The height of the response antenna will be fixed at the current value.
The path profile image will display the criterion used to calculate the antenna height. Click OK to change the antenna height according to the calculated value. To discard the calculated value, click Cancel.
