[TowerTalk] ground and conductivity

[Martin AA6E]

>From the ARRL Antenna book:

Surface Type              Conductivity (S/m)

Fresh water                 .001
Salt water                 5.0
Pastoral hills (dallas!)    .0303
etc

Fresh water is about the worst ground system there is, according to
this table.  In terms of conductivity, anyway.  It does have a very
high dielectric constant, which helps reflect RF, too.
