To All from PA0SE
Computer program Antenna Optimizer by K6STI permits to calculate
the near field of an antenna up to a distance of 2km. I did so for a vertical
for 9kHz. I had to make it 180m high before computation was
possible.
The field is computed for a radiated power of 1kW. But what matters
is the way the field strength changes with distance.
Sorry for the poor quality. The file cannot be saved outside
the AO program or whatever that is called in computer speak. So I had to print
them using "Print Screen" and scan the printed result.
I first included the near magnetic field as well but the Reflector
apparantly did not accept the file (50kB). When I see this message has been
accepted by the Reflector I will send the magnetic field values by a separate
e-mail.
