Notes:-
1. The daytime coverage radius of this transmission has been calculated at 25km at its maximum based on a ‘nominated’ point with the following AMG co-ordinates: Zone 55; Easting 693775; Northing 6093950. The purpose of this is to match the directional radiation pattern to a notional omni directional pattern to readily represent the likely coverage that would be achieved with the directional radiation pattern and transmission site.
2. The day time coverage radius of a Medium Frequency service is defined by the estimated field strength contour of 54 dBuV/m, which is the protected field strength in the presence of man made radio noise alone in a rural radio noise environment. But this estimated coverage, to obtain the defined quality of service for that radio noise environment, could effectively reduce when considering the addition of natural noise. In general, the night time coverage, to obtain the same quality of service, is smaller than the daytime coverage due to co and adjacent channel sky wave interference acting as additional noise contribution.
