All of the data I have seen shows the effect rapidly dimiminishes as
the frequency moves below upper VHF and is immeasurable at HF and
The only noticeable effect of weather is in noise (from static
discharges) and to a smaller extent conductivity of upper layers of
soil (from moisture changes).73, Tom W8JI
