Once again the theory is outvoted by personal endorsements.
Frankly, models can save you a lot of time by having you NOT put up
something that won't be an improvement. Chances are quite good if you
model two antennas and compare the results, the codes will get the
ranking right.
Of course, if you like working outdoors with wires, go ahead.
