[Antennaware] Traps

[Frank]

Hi
I follow with great interest the discussion regarding using a trap in the inverted L-config for the
80/160m bands.
Iam in the processing of building one antennas and was thinking of more like a battle creek antenna without the 40M trap.But then I recall someone writing somewhere about using a  LC parallell
circuit designed for the geometrical center of the two freq. i.e for 1.82 and 3.6 = 2.56 Mhz
As i understand on 160m the lc-circuit would act as a inductor  and on 80M would act as a capacitor thereby using the whole antenna on both bands.Could a coaxial trap be used for this
and where on the antenna would this be placed ?
Has anyone tried this ?
