Shouldn't you say "Computer simulations do not model this". Decca did a

lot of

measurements when they developed Navigator, and the physics always has the

last

word. The question should therefore be "what is wrong with the computer

model?"

The computer did not simulate the Decca mast but the small L-antenna used by
Jim.
