If the L and R branches have the same L, the desired
stagger-tuning/broadbanding effect is not achieved. . . In a nutshell,
a VHF suppressor should have roughly the same amount of VHF current
passing through each branch; the intrinsic L of the R should be as low
as possible; and the EM fields of the L and the R should be at right
angles so that they do not like a single inductance. IOW -- Series-R in
the suppressor L is a plus. Series-L in the suppressor R is a minus.
