Not only is it easier, making scaled drawings of your site is usually
required for building permits. So, I use those
drawings in the implementation of my station. The scaled drawings take any
guess work out of the
picture. As I contemplate buying/building new antennas, I place little
"shrimpboats" (as I call them) on the
scaled drawings to see if whatever I'm contemplating will fit.
All this in the theme of: "It's easier to simulate/test it on the ground
before it goes on the tower."
