[TowerTalk] Antenna Modeling

[David Gilbert]

Same here.  Trial and error may eventually work, but most likely you 
won't know why.  Modeling, especially if you investigate the currents 
and their phasing, will help you learn and understand why something 
might work or not work.  "Ham" radio doesn't mean being ignorant of the 
stuff behind what we do.

There are pitfalls with modeling of course, but doing things like a 
running a sensitivity analysis (tweaking dimensions to see if the 
changes make sense) can minimize that.  I learned more about antennas 
from playing around with EZNEC+ than I ever did from any other source.
