Below is a NEC4.2 plot of the elevation pattern fields at an h-distance of 1 mile from the base of a monopole, based on the same model parameters as in my original post above. A comparison is shown for that sector for the fields at 2 miles, also. These calculations include the surface wave, which is necessary to calculate/plot this scenario accurately. Z = elevation in meters above a flat Earth, and E = field intensity in mV/m Note that the two fields shown there have a ~1/r relationship, which is characteristic of a space wave. That relationship will be maintained for very low, but not zero-angle propagation paths reaching to, and reflected by the ionosphere. _____ As a workaound, a Ø can be included in posts here by entering Alt+Ø216 using the number keypad.
