Maybe this info will help,
Look at L.B. Cebik - W4RNL's site, near bottom of the page "Antenna Modeling
Notes" and listed is Modeling Trap Antenna's.
http://funnelweb.utcc.utk.edu/~cebik/radio.html
He gives some examples of values of the traps and other good info on page
two of Modeling Trap Antenna's.
