To try to answer some unanswered questions about the relationship of trap
Q, wire size, and performance, I have begun some systemmatic modeling of
the 10-20 meter dipole as a test case (the first among many). The initial
results are in a post called "Systemmatic Trap Modeling" at my site, and
the graphs (multi-color to compete with Mars pictures, as if I could) may
be of interest to some. The entry is incomplete (and may always be so,
given the number of possible variations on the trap theme), but is
indicative of why low and high Q traps do what they do. As usual, fat
wire and high Q win over skinny wire and low Q--but you already know that.
How big the score is may surprise you--at least a little bit. More will
be added as it becomes available.
