Ground Conductivity Atlas
Here’s a useful PDF that I found online. I have [over the years] searched for information relating to the ground conductivity in my local area. This is extremely useful information when modelling antennas at their actual working heights.
Being able to adjust the ground conditions that are pertinent at your own QTH, makes modelling just that little bit more accurate.
I’m happy that here on the Western border of ‘Eastern England‘ we have the best ‘Ground’ in the UK at 0.01s/m and a Dielectric Constant of 14 [Ref: EZNEC – W7EL]
