At Dayton/Xenia antenna forum this year 2022, N9NB had a pretty
interesting talk on low band verticals. The key take-away from that was
that you could reasonably determine your actual ground loss based on VNA
measurement of your antenna, and comparing it with the model of same. Of
course the caviets apply - the more simple and idealized your antenna is
in reality, the easier it is to closely model the reality of the install
and get a better set of ideal numbers to compare the measured against.
The likely unknown here is the soil characteristic plugged into the
model, as compared to what we have. :)
